This release features code to compute the relaxation complexity rc(X,Y) of a set X with respect to a set Y. The corresponding SCIP code consists of three models: a compact model, a separation-based model, and a branch-and-price model. The models can be enhanced by propagation and symmetry handling techniques as well as heuristics
