Optimization deals with selecting the simplest option among a number of possible choices that are feasible or do not violate constraints. Python is used to optimize parameters in a model to best fit data, increase profitability of a possible engineering style, or meet another form of objective which will be described mathematically with variables and equations.
pyOpt is a Python-based package for formulating and solving nonlinear constrained optimization problems in an efficient, reusable and portable manner. Python programming uses object-oriented concepts, such as class inheritance and operator overloading, to maintain a distinct separation between the problem formulation and the optimization approach used to solve the problem.
All optimisation downside solvers inherit from the Optimizer abstract category. The category attributes include the solver name (name), an optimizer kind symbol (category), and dictionaries that contain the solver setup parameters (options) and message output settings (informs). The class provides ways to check and alter default solver parameters (getOption, setOption), as well as a method that runs the solver for a given optimisation problem (solve).
A number of constrained optimization solvers are designed to solve the general nonlinear optimization problem.
To solve an optimization problem with pyOpt an optimizer must be initialized. The initialization of one or more optimizers is independent of the initialization of any number of optimization problems. To initialize SLSQP, which is an open-source, sequential least squares programming algorithm that comes as part of the pyOpt package, use:
>>> slsqp = pyOpt.SLSQP()
This initializes an instance of SLSQP with the default options. The setOption method can be used to change any optimizer specific option, for example the internal output flag of SLSQP:
>>> slsqp.setOption('IPRINT', -1)
Now Schittkowski’s constrained problem can be solved using SLSQP and for example, pyOpt’s automatic finite difference for the gradients:
>>> [fstr, xstr, inform] = slsqp(opt_prob,sens_type='FD')
By default, the solution information of an optimizer is also stored in the specific optimization problem. To output solution to the screen one can use:
>>> print opt_prob.solution(0)
The problem is taken from the set of nonlinear programming examples by Hock and Schittkowski and it is defined as
min − x1x2x3
subjected to x1 + 2x2 + 2x3 − 72 ≤ 0
− x1 − 2x2 − 2x3 ≤ 0
0 ≤ x1 ≤ 42
0 ≤ x2 ≤ 42
0 ≤ x3 ≤ 42
The optimum of this problem is at (x1∗ , x2∗ , x3* ) = (24, 12, 12), with an objective function value of f ∗ = −3456, and constraint values g (x∗ ) = (0, −72).

Solving non-linear global optimization problems could be tedious task sometimes. If the problem is not that complex then general purpose solvers could work. However, as the complexity of problem increases, general purpose global optimizers start to take time. That is when need to create your problem specific fast and direct global optimizer’s need arises.
We have an specialized team with PHD holders and coders to design and develop customized global optimizers. If you need help with one, please feel free to send your queries to us.
We first understand the problem and data by visualizing it. After that we create a solution to your needs.
Please do read to understand what a solver is and how it works - If you want to create your own simple solver. This is not exactly how every solver works, however, this will give you a pretty solid idea of what is a solver and how it is supposed to work.
WordPress is an open source Content Management System (CMS), which allows the users to build dynamic websites and blog. WordPress is the most popular blogging system on the web and allows updating, customizing and managing the website from its back-end CMS and components.
This article will teach you the basics of WordPress and how to hire a wordpress expert freelancer for building an amazing wordpress project. Here you will also find details about how to hire a wordpress theme developer, wordpress plugin developers on Toogit. With the help of these experts you can create websites with ease. Before posting a wordpress project it is important to know that Wordpress is divided into 2 major modules backend (also called wordpress admin) and frontend (A wordpress site).
Project Management is the key to successfully and effectively manage every task that needs to be completed in a project. When a team is involved in a project, it becomes essential to have some sort of project management system to keep track of the work growth.
Many people opt for expensive project management software when they need a project management tool. But did you know you could do that with WordPress? Many people believe that WordPress is just good for publishing. But the increasing number of websites built with WordPress for different purposes such as e-commerce is a proof that WordPress can do more than you think.
One of the most often asked question to search engines by users is "Do I have to pay to use WordPress?". And everytime search engines tell them that WordPress is a free and open source software, which is usually followed by, “Why is WordPress Free?”. In this article, we will discuss why WordPress is free, the costs of running a WordPress site, and what’s the catch?
WordPress is an open source software. It is free in the sense of freedom not in the sense of free beer:
You may ask what is the difference between these two?
Open Source software comes with freedom for you to use, modify, build upon, and redistribute the software in any way you like. However, there might be costs involved somewhere.
User Management: It allows managing the user information such as changing the role of the users to (subscriber, contributor, author, editor or administrator), create or delete the user, change the password and user information. The main role of the user manager is Authentication.
Media Management: It is the tool for managing the media files and folder, in which you can easily upload, organize and manage the media files on your website.
Theme System: It allows modifying the site view and functionality. It includes images, stylesheet, template files and custom pages.
Extend with Plugins: Several plugins are available which provides custom functions and features according to the users need.
Search Engine Optimization: It provides several search engine optimization (SEO) tools which makes on-site SEO simple.
Multilingual: It allows translating the entire content into the language preferred by the user.
Importers: It allows importing data in the form of posts. It imports custom files, comments, post pages and tags.
Building an enterprise website is, by definition, a huge undertaking. The last thing you want is to invest your project’s resources into the wrong framework, which could potentially set you back thousands of dollars and countless wasted hours.
Naturally, many people are big fans of WordPress! It’s a well-supported, flexible, and open-source framework that’s powerful enough to develop all manner of websites. As a platform that’s now over ten years old, it’s stable and packed with extensible features that enable you to build almost any website or web app you can imagine.
1. It’s Flexible, Open-Source, and Free
Of course, WordPress is open-source. It means the original source code is freely available for personal and commercial use, and you can redistribute it or modify it however you see fit.
This makes WordPress an ideal candidate for enterprise sites for a number of reasons. Firstly, given its dominance on the web, you’ll have one of the largest developer communities at your back. This means you’ll receive regular security and feature improvements without paying any additional fees.
Secondly, it’s easily customizable for your own specific needs from the very beginning. In other words, WordPress is incredibly flexible with regard to any bespoke functionality you need to build or source.
2. WordPress is Ready for Responsive Development
Responsive development is what makes a design work across all devices, whether that’s a desktop or smartphone display. Since WordPress enables you to build completely custom themes, your enterprise site can sport whatever skin you need it to. Considering that mobile devices are the primary driver for digital media growth, your enterprise site definitely needs to be responsive.
3. WordPress is Scalable
Scalability affects your ability to serve increasingly large numbers of visitors. If no effort has been made here, even a simple website will crash after receiving one too many visitors at once.
4. It Offers Multisite Functionality
Simply put, Multisite is when you operate multiple websites from one central hub. WordPress supports running as many sites as you need from one core installation
5. It Has Built-In User Role Management
Role management essentially gives you the power to control who can access certain areas of your site. One of the guiding principles for security is to only offer access to the essentials a user needs to carry out their tasks.
6. WordPress Has Its Own REST API
We would be remiss to discuss WordPress viability for enterprise sites without pointing out the REST API. Endpoints were included in a recent update, and it means you can now tie WordPress to a number of external apps and languages by using technology such as AJAX and JSON.
Before you start with hiring It is necessary to catch what you are planing to develop and who is the right candidate to achieve your goals.
Here I am describing few points which will help you to find the right developer for your wordpress project,
1. Wordress developer must be aware of the basics of HTML and CSS. If you are a wordpress developer and are not aware of these concepts, then I suggest first go through short tutorials on HTML and CSS.
2. Good knowledge about trending database & experience in complex query.
Every wordpress developer should be able to do following:
Review & hire your best wordpress developer.
If you are planing to develope a big project with wordpress. Please look at the following point before choosing the wordpress as best fit for your project.
Using several plugins can make the website heavy to load and run.
PHP knowledge is required to make modifications or changes in the WordPress website.
Sometimes software needs to be updated to keep the WordPress up-to-date with the current browsers and mobile devices. Updating WordPress version leads to loss of data, so it is recommended to keep a backup copy of the website as required.
Modifying and formatting the graphic images and tables is difficult.
If you want open-source flexibility and a strong community behind you, WordPress is a fantastic choice for your next enterprise site. Of course, you should still carefully examine your needs and carry out some research to find the best fit for your project. However, with its current dominance and upward turn, WordPress is clearly a tantalizing option.
Every satisfied customer on every website starts in the hands of a experienced web designer. This professional has the ability to capture the client’s vision, bring the design elements to life, and ultimately create a website that appeals to consumers. This is not easy task since it involves both creative and technical abilities, so a top web designer is experienced in many different disciplines.
Likewise, an in-demand website designer will also have insights into the business and marketing worlds to understand how a website can meet a client’s needs, convey their brand, and help embrace new customers online. This knowledge is used to maximize things like lead generation and overall engagement levels.
Web designers must always begin by considering a client’s website objectives and then move on to an Information Architecture (IA) to set a website’s information hierarchy and help guide the design process. Next, web designers can start creating wireframes and finally move to the design stage. Web designers may use several basic design principles to achieve an aesthetically pleasing layout which also offers excellent user experience.
Balance – It’s important for web designers to create a balanced layout. In web design we refer to heavy (large and dark colors) and light (small and lighter colors) elements. Using the correct proportion of each is critical to achieving a balanced website design.
Contrast– In color theory, contrasting colors are ones placed opposite one another on the color wheel (see also complementary colors). Web design offers a few other areas where contrast is applicable. Designers look at contrasting sizes, textures and shapes to define and draw attention to certain sections of the website.
Emphasis– We touched on this a bit when discussing contrast. Emphasis is a design principles founded in the intentional “highlighting” of certain important elements of the website layout. It’s important to note that if you emphasize everything on the page you end up emphasizing nothing. Imagine a page in a book where 80% of the content is highlighted in yellow…does anything really stand out? This is the time to take a look at that Information Architecture for direction.
Consistency – Also called repetition or rhythm, consistency is a critical web design principle. For example, clean and consistent navigation provides the best user experience for your website visitors.
Unity – Unity is the relationship between the various parts of the website layout and the composition as a whole. Based in the Gestalt theory, unity deals with how the human brain visually organizes information by grouping elements into categories.
Web developers, sometimes called programmers, take the design created and build a fully functioning website. To put it (very) simply, think of the design as a non-interactive “picture” of a website. Developers take that design and break it up into it’s components. They then either use just HTML or a more dynamic approach incorporating programming languages such as PHP to develop the various website pages. More advanced web developers may choose to utilize a Content Management System (CMS) like WordPress or Joomla in order to streamline development and allow clients an easy way to maintain and update their website.
Web developers may convert a static layout into a dynamic website by using image and content sliders, active states for links and buttons, and other interactive elements.
It pays to do a little bit of homework before hiring a web designer since it can have a drastic effect on the overall price and the quality received. For example, a simple website without any large customizations can be launched with a pre-made theme at a minimal cost. This may not be suitable for websites anticipating lots of custom layouts and/or extensive traffic, so it’s good to know up front what type of designer will be required or if you’ll also need a developer.
Take a look at an example web design project description. Keep in mind that many people use the term “job description,” but a full job description is only needed for employees. When attracting a freelancer as an independent contractor, you typically just need a requirement of work, job post, or any other document that describes the work to be done.
ABC Company is looking for a web designer to create a custom theme for our e-commerce store. This project will be to create a responsive, mobile-friendly design.
Mock-ups for each page of e-commerce site (approximately 20 pages)
Custom navigation and HTML elements
Graphics integrated into two homepage carousels (12 images total)
Setup of online shopping basket
Deadline for deliverables:
All tasks must be completed by <date>.
This project requires the following skills:
Expertise working with <design software>, <mobile/responsive framework>, <Adobe Photoshop>, or <CMS template builder>
E-commerce experience is a plus
Understands responsive design
The work will also require a great view for detail and preliminary retail experience, preferably in the electronics/automation industry. We would like to begin this project no later than <date>, so we plan on hiring a candidate by the end of the week.
After posting a detailed, well-thought-out project description that defines what you’ll need from your web designer, it’s time to start analyzing proposals. How do you select the top talented designer for your project?
When it comes to finding the top talented web designer, start by reviewing for portfolio samples that match your requirement. Be sure to ask freelancers about their experience with other facets of design as well, and consider the overall goal for the website being built.
Finally, it’s important to verify that a web designer understands the brand in question and its overall goals online. A qualified professional will be able to give a list of any expected obstacles, plus estimate the amount of time the project will take and the total cost. Since complex website projects could require months to complete, a good working relationship is essential.
With the right freelance web designer, you can end up with a finished product that brings your vision to life. Just take the time to create a detailed project description, review each freelancer’s proposal and portfolio, and ask them a few web design interview questions to determine if they’re the right fit for the project.
