#
# Cross-check BlockSolverConfig for a PURE-BINARY BinaryKnapsackBlock: it
# attaches EVERY solver / formulation that must give the SAME integer optimum,
# so that a single sweep cross-checks them all (see batch):
#
# - :MILPSolver exact MIP (the reference optimum)
# - CoreDPBinaryKnapsackSolver exact core / non-dominated-state DP
# - GreedyRelaxationBinaryKnapsackSolver relaxation: must BRACKET the optimum
# - BranchAndXSolver, once per exploration mode (best-/depth-/breadth-first,
# parallel depth-first, per-node parallel solvers, cut separation): all are
# exact and must hit the same optimum.
#
# The reoptimization mode (intReoptimize) is intentionally left out for now (a
# known issue over many re-solve cycles). The per-solver ComputeConfig are
# factored into the *Cfg.txt fragments (the MILP/DP/CDP/GR ones are shared
# with BSPar-mixed.txt) and the BX modes share BX-baseCfg.txt, overriding
# only the mode-specific parameters via '*BX-baseCfg.txt +': no duplication.
# NOTE: an overriding ComputeConfig that is not the last in the list must end
# with the '*' extra-Configuration pointer, or the parser runs into the next.
