Detailed Description

Heuristic to solve the spatialization problem across a landscape for multiple operating areas.

MIP forest planning problems tend to be symmetrical and hard to solve with a regular MIP solver; this heuristic quickly generates a good enough starting solution. Before using this class the user must have set all the parameters of a vector of FMTOperatingArea so the heuristic can set the constraints and variables of each operating area into the matrix.
