OR-TOOLS

OR-Tools is an open-source, quick, and portable combinatorial optimization programme. The initial version was published on GitHub in September 2015, and it has since progressed to version 7.2, which was published in July 2019.

It is used for  Optimizing and  tackling the world’s toughest problems in vehicle routing, flows, integer and linear programming, and constraint programming.Essentially, optimization is the process of identifying the optimal solution to a problem from a vast range of alternative options. We all have limited resources and time, and we all want to make the most of it.We all know how essential optimization is in data science, whether it is the chore of organising the sequence in which you will answer emails or moving to a different route back home to reduce traffic problems.

 One of the primary objectives of a data scientist is developing a model that suits the problem, such as determining optimum heuristics, minimising function losses, and so on. As a result, understanding optimization frameworks is critical. The first problem we 

will look at is linear optimization.

Linear optimization is a strategy for finding the optimum solution to a problem that is represented by a collection of linear relationships. Google offers three solutions to the linear optimization issue.

Glop- It is an open source in house solver. It is compatible with the linear solver wrapper.

Add On For Google sheet- allows you to solve linear optimization problems in a spreadsheet by adding variables and constraints

Apps Script- It depends  on Glop for pure linear Optimization.

Advantages of Google Developer Tools

The fundamental goal of utilising OR-Tools is to identify the best (optimal) answer to a problem when there are numerous alternative solutions, which complicate calculations.

Google OR-Tools has several technological advantages over competing alternatives, including:

  • A flourishing community provides time-tested stability and continual progress. This translates into frequent updates, bug fixes, and new features for your project.
  • High performance that is consistent thanks to multithreaded algorithms that are designed for complicated calculations. This guarantees that you obtain results quickly without incurring additional development and hardware costs.
  • Flexible constraint control and infrastructure selection allow for a rapid and easy deployment. This means you receive the best outcomes while spending the least amount of money on infrastructure.

Use Cases of Google OR-Tools

Routing

  • Routing is one of the most difficult and fascinating programming jobs. Google OR-Tools has specific algorithms for node-based and arc-based routing issues.
  • Create the quickest path for your couriers to use while delivering items to numerous addresses. Furthermore, you might include weight and time frame constraints to deliver large items first or schedule delivery when clients are at home.
  • Plan the quickest path for a fleet of vehicles to take in order to cover all streets within a certain area. Google Street View vehicles are powered by a similar algorithm.

Packing

  • Calculate the minimum number of delivery vehicles or containers required to accommodate the customer’s consignment. For the best results, the algorithm can employ both weight and linear dimensions.
  • Calculate the maximum number of parcels your delivery vehicle can hold in order to improve transportation service efficiency. This algorithm guarantees that your delivery fleet’s volume and load-bearing capability are fully used.

Scheduling

  • Create an automated scheduling system for schools, colleges, and universities to eliminate the need for students to travel across campus between classes.
  • Provide scheduling tools for small and large enterprises that work various shifts and want to keep their employees happy by taking their preferences into account.

Barriers of OR-Tool Adoption

The extensive solution library

While it simplifies the solution of certain difficulties, choosing the optimal choice for your unique project can be difficult, even for an experienced development team.

This library’s lack of software engineering experience.

Google OR-Tools have less  practical experience in  implementing the solution into real-world applications. They will require more time to become acquainted with the technology, delaying the project timeframe by weeks, if not months.

Conclusion:

Recognizing the use of OR-Tools in a number of business implementations, Freshcode engineers, have become acquainted with the library and its possibilities. It is  recommended for numerous clients and effectively deployed routing solutions.
