For VRPTW, routes are directed so the current `brokenPairsDistance` implementation compares directed routes (through directed neighbours).
* For CVRP, we should probably implement a a version that co…

For testing/debug purposes, we should probably turn on sanitizers in order to try and catch potential code problems. A good place to start would be to add `-fsanitize=address -fno-omit-frame-pointer` …

Hi there!
Recently I am trying to run an basic immune genetic algorithm based on DEAP。
(For FeatureSelection)
### **background**
The basic principle is to calculate the selected probability of e…

This issue keeps track of plans for a new major release of VRPLIB. This is a long-term goal and will be developed in parallel with the needs of PyVRP.
`vrplib` (v1) was originally designed to suppo…

Thanks for sharing the pre-trained models.
But in the pretrained directory, I only saw two POMO based neural solvers: "POMO-CVRP" and "POMO-VRPTW". In the paper, there should be another four single…

## Description
The platform will support at least 2 optimization problems:
- Time Slotting problem
- Vehicle Routing problem
The system stores specified problems. The associated data can be stored fo…

#### Describe the solution you'd like
Currently, all vehicles can be used to visit all clients. This might be OK in static problem settings like the ones we currently support, but falls apart when …

Here's a list of common VRP variants. I thought it would be useful to have this somewhere for reference and link this to related issues as well. The list is (obviously) not exhaustive, but should help…
