LINDOGlobal 309
BRANCH LIMIT (integer)
This is the limit on the total number of branches to be created during branch-and- bound in GOP tree. The
default value is -1, which means no limit is imposed. If the branch limit is reached and a feasible solution
was found, it will be installed as the incumbent (best known) solution.
(default = -1)
CORELEVEL (integer)
This controls the strategy of GOP branch-and-bound procedure.
(default = 14)
+2 LP convex relaxation
+4 NLP solving
+8 Box Branching
OPT MODE (integer)
This specifies the mode for GOP optimization.
(default = 1)
HEU MODE (integer)
This specifies the heuristic used in the global solver to find a good solution. Typically, if a heuristic is used,
this will put more efforts in searching for good solutions, and less in bound tightening.
(default = 0)
0 No heuristic is used
1 A simple heuristic is used
SUBOUT MODE (integer)
This is a flag indicating whether fixed variables are substituted out of the instruction list used in the global
solver.
(default = 1)
0 Do not substitute out fixed variables
1 Substitute out fixed variables
LSOLBRANLIM (integer)
This value controls the branch limit until finding a new nonlinear solution since the last nonlinear solution
is found. The default value is -1, which means no branch limit is imposed.
(default = -1)
USEGOP (integer)
This value determines whether the global optimization will be used.
(default = 1)
0 Do not use global optimization
1 Use global optimization
