Add LKH baseline solver #4

Closed fillipe-gsm closed 3 years ago

fillipe-gsm commented 3 years ago

The binary file was compiled from https://github.com/cerebis/LKH3

Since this is a C file, the meat of the PR is in the interface: temporary TSPLIB and parameter files are created for a given instance, the solver is called, its solution is written in another temporary file, which is finally read and converted into a solution.
