In this post, we’ll develop a construction heuristic to build reasonable (start) solutions for the knapsack problem. Why use Construction Heuristics? Construction heuristics offer the advantage of quickly leading to acceptable solutions. Unlike more complex optimization algorithms, they are easy to implement and require less computational power. These heuristics are particularly well-suited for handling large… Read more The use of Construction Heuristics
If you happen to have to solve TSPs or some special type of VRPs – i.e. capacitated or with timewindows and other constraints – you might want to have a look at Google OR-Tools. The library contains a wide variety of heuristics for different problems primarly based on google’s excellent constraint programming solver. The library… Read more Solve TSP Instance using Google OR-Tools
This post shows a simple implementation using R to solve a given TSP (Traveling Salesperson Problem) instance using the Pilot Method. The whole R script can be accessed here on my gist. How does the Pilot Method work? The Pilot Method is a construction heuristic to build (i.e. initial) solutions. The method tries to avoid… Read more Solve TSP using Pilot Method
