IAimmsMathProgramCallback::Phase Enumeration

The Phase enumeration describes all possible solvers phases of the algorithm, as passed via the phase input argument of the PassPhaseInfo method.

C++

enum Phase {

  PHASE_BARRIER = 0x00000004,
  PHASE_NETWORK = 0x00000008,
  PHASE_BARRIER_CROSSOVER = 0x00000010,
  PHASE_NETWORK_CROSSOVER = 0x00000020,
  PHASE_MIP = 0x00000040,
  PHASE_POSTSOLVE = 0x00000080,
  PHASE_MIP_POSTSOLVE = 0x00000100,
  PHASE_SIFTING = 0x00000200,
  PHASE_PRIMAL_SIMPLEX = 0x00000400,
