Does VROOM support vehicle number reduction ?
If not how hard would it be to add this feature ?

Heuristic parameters tuning determine the initial solutions we use during the search. This still needs to be refined for VRPTW. It also requires updates for CVRP as a few things changed since the last…

The current VRPTW heuristic considers all vehicles sequentially to build routes using remaining jobs. Vehicles are sorted _a priori_ based on capacity and time window length. This makes perfectly sens…

During the local search phase, we apply a set of operators on pairs of (different) routes. As a result, the local search phase is unable to fix problems by moving jobs around in a *single* route. This…

We have heuristic approaches for both VRPTW (based on Solomon I1) and CVRP (custom clustering scheme). In both cases, parameters tuning are highly dependent on whether we face single or multi-depot si…

Once #137 is available, we'll need to apply a local search phase to the heuristic solutions as a next step toward #113.
The easiest way to do that would be to re-use the outline of the CVRP local s…

While working on #140, I noticed a surprising behaviour: when comparing default "empty" amounts created with `amount_t(0)`, both `operator

学长您好,偶然学习到您的程序,算法实现非常严谨。但有一个问题,观察您上传的result,感觉fitness随generation收敛速度有些慢,甚至感觉没有得到实质性的收敛,我初学可能理解不是很深刻,希望能得到您的指教。
BYR

* I noticed that you include all headers in the `class.h` files although some of them would only be required in the `class.cpp` file. By moving some `#include`s around I can reduce the time for a clea…

Very thanks for your code. I'm very interested in applying genetic algorithm in vehicle route problem (VRP).
In the code, I turned this code for VRPTW into a general VRP problem by doing the follo…
