USE AUTOMATIC EXPANSION

Name: USE_AUTOMATIC_EXPANSION Type: bool Default Value: true Available Options: true, false I told you we had the best gear. Preprocessing

UB FREQUENCY

Name: UB_FREQUENCY Type: integer Default Value: 4 Range: [1−2,147,483,647] This option sets how often the solver should solve local optimisation

STRONG BRANCHING VARIABLE COUNT

Name: STRONG_BRANCHING_VARIABLE_COUNT Type: integer Default Value: 100 Range: [0–2,147,483,647] Requires: BRANCHING_STRATEGY = STRONG_BRANCHING When BRANCHING_STRATEGY = STRONG_BRANCHING , this option sets the

OBBT MAX ITERATIONS

Name: OBBT_MAX_ITERATIONS Type: integer Default Value: 1 Range: [1−2,147,483,647] This sets the maximum number of passes for OBBT.

OBBT MAX DEPTH

Name: OBBT_MAX_DEPTH Type: integer Default Value: 2,147,483,647 (unlimited) Range: [1−2,147,483,647] This sets the maximum depth in the branch-and-bound tree at

NUM CORES

Name: NUM_CORES Type: integer Default Value: 1 Range: [1 – 2.e9] Number of MPI processes to spawn. If your problem

MILP LB TIMEOUT

Name: MILP_LB_TIMEOUT Type: double Default Value: 5 Range: [1–1.79e308] This option sets the timeout (in real-time seconds) for the MIP

INTEGRALITY VIOLATION TOLERANCE

Name: INTEGRALITY_VIOLATION_TOLERANCE Type: double Default Value: 1.e-3 Range: [0–1] Integrality violation tolerance is the acceptable violation before the solver determines

INFINITY

Name: INFINITY Type: double Default Value: 1.e7 Range: [0−1.e7] As I hope you know, deterministic global optimisation only works on

HEUR NL FEASIBILITY PUMP

Name: HEUR_NL_FEASIBILITY_PUMP Type: bool Default Value: true Available Options: true, false Enables or disables the Nonlinear (NL) Feasibility Pump heuristic.
