• Find substring ignoring specified characters

  - by Fredy Treboux

  Hello, please, does any of you knows and can share an easy/clean way to find a substring within a string, but ignoring some specified characters to find it. I think an example would explain things better: string: "Hello, -this- is a string" substring to find: "Hello this" chars to ignore: "," and "-" found the substring, result: "Hello, -this" Using Regex it's not a requirement for me, just added the tag because it feels related.

• Travelling Salesman Problem Constraint Representation

  - by alex25

  Hey! I read a couple of articles and sample code about how to solve TSP with Genetic Algorithms and Ant Colony Optimization etc. But everything I found didn't include time (window) constraints, eg. "I have to be at customer x before 12am)" and assumed symmetry. Can somebody point me into the direction of some sample code or articles that explain how I can add constraints to TSP and how I can represent those in code. Thanks!
