LINDOGlobal 297
NLP REDGTOL (real)
This is the tolerance for the gradients of nonlinear functions. The (projected) gradient of a function is
considered to be the zero-vector if its norm is below this tolerance.
(default = 1e-7)
NLP USE CRASH (integer)
This is a flag indicating if an initial solution will be computed using simple crash routines.
(default = 0)
0 Do not use simple crash routines
1 Use simple crash routines
NLP USE STEEPEDGE (integer)
This is a flag indicating if steepest edge directions should be used in updating the solution.
(default = 0)
0 Do not use steepest edge directions
1 Use steepest edge directions
NLP USE SLP (integer)
This is a flag indicating if sequential linear programming step directions should be used in updating the
solution.
(default = 1)
0 Do not use sequential linear programming step directions
1 Use sequential linear programming step directions
NLP USE SELCONEVAL (integer)
This is a flag indicating if selective constraint evaluations will be performed in solving a nonlinear model.
(default = 1)
0 Do not use selective constraint evaluations
1 Use selective constraint evaluations
NLP PRELEVEL (integer)
This controls the amount and type of NLP pre-solving.
(default = 126)
+2 Simple pre-solving
+4 Probing
+8 Coefficient reduction
+16 Elimination
+32 Dual reductions
+64 Use dual information
+512 Maximum pass
NLP ITRLMT (integer)
This controls the iteration limit on the number of nonlinear iterations performed.
(default = GAMS IterLim)
NLP LINEARZ (integer)
This determines the extent to which the solver will attempt to linearize nonlinear models.
(default = 0)
