- Implement time lag constraints for RCPSPs:
- min time lag: start[t2] >= start[t1] + offset, offset >= 0
- max time lag: start[t2] <= start[t1] + offset, offset >= 0
- Replace start_after_nunit with start_to_start_min_time_lag since it has the same semantic and the new name is more coherent with the new complementary start_to_start_max_time_lag. Another choice was to have a generic start_to_start_with_time_lag constraint wich positive or negative offset, but it ouwld make the understanding more complex for the user, and the literature seems to use more the 2-constraint formalization with positive offsets (as proposed in this PR)
- Add a new Iterative SGS with Filtering Buffer method to construct a feasible schedule for RCPSP with time lags from a given task permutation.
- Add unit test functions for RCPSPs with time lag constraints
…arning effect - should be coherent with Le, Roussel, Lecoutre paper in CP25 - monolothic and sequential cp approaches (forward and backward approaches) - postprocess solver to compute pareto fronts
- backward approach - pareto approach
…he satisfy function
…rename start_after_nunit to start_to_start_min_time_lag for coherency and completeness
