Hi all! I would like to create a QGis plugin to solve the Vehicle Routing Problem (VRP) using Evolutionary Computation techniques (Genetic Algorithms and stuff like that). I have some initial questions, so if someone can help-me, I'll appreciate it very much.
1. What programming language should i use? I know that there's the possibility to create plugins in Python or C++, but the Python Plugin Installer, as the name states, can only be used for python plugins. The problem of using python is about speed/performance, because VRP is a very hard problem, especially when is solved using Evolutionary Computation techniques. There seems that i have 3 options: a) Do all the work in python, using some libraries to speed up the thing (like scipy). b) Build the interface in python and the core library in C++. I don't know if python and C++ can integrate well. I don't know either if this can be done, because C++ has to be compiled for the client machine (that can be windows, linux, ...) c) Build the interface in python and the core library in java. I don't know if python and java can integrate well too, but java can run in almost every platform and is fast. 2. For the plugin to work, i need to find the shortest path between any two points on a POINT layer, using a LINESTRING layer for the road network. In the new QGis development version there's a plugin/tool named "shortest path". Can i use it to calculate this distances from a python plugin? Any help or advice is very appreciated.
