Parameters

• BCP Parameters
  A description of the various BCP parameters that can be used for the LP process and the TM process can be found in the Doxygen notes on the COIN website. In Run/par.par there is a list of those parameters which must be set for our application.
  • BCP_LpValueIsTrueLowerBound is set to 0, since we are generating columns and cannot say that the intermediate LP solutions give a true lower bound.
  • BCP_SolveLpToOptimality is set to 1, since we need the optimal dual variables to generate columns. We do not want the LP solver to stop once it has reached the dual objective limit.
  • BCP_DoReducedCostFixingAtZero is set to 0, since we do not want to allow for reduced cost fixing while we are generating columns.
  • BCP_DoReducedCostFixingAtAnything is set to 0, since we do not want to allow for reduced cost fixing while we are generating columns.

• TM/AAP_tm_param.cpp - AAP_datafile: The location of the AAP instance data file.
• LP/AAP_lp_param.cpp - AAP_StrongBranch_Can: The number of candidates to produce for strong branching.
