# A txt description of a BlockSolverConfig for the inner Block of an
# InvestmentBlock (a UCBlock, or a TwoStageStochasticBlock of UCBlock), to be
# solved by a :MILPSolver; the InvestmentFunction gets it from IFCfg.txt
#
# HiGHS by the simplex method: where the inner Block is infeasible the
# InvestmentFunction cuts the point away with the homogeneous multipliers of
# the dual direction (intHomogeneousDirection), and without the cut the
# bundle stops above the optimum
