addgencons

Purpose
Adds one or more general constraints to the problem.
Each general constraint y = f(x1, ..., xn, c1, ..., cn) consists of one or more (input) columns xi, zero or more constant values ci and a resultant (output column) y, different from all xi. General constraints include maximum and minimum (arbitrary number of input columns of any type and arbitrary number of input values, at least one total), and and or (at least one binary input column, no constant values, binary resultant) and absolute value (exactly one input column of arbitrary type, no constant values).

Arguments
prob 
The current problem.
contype 
Integer array of length ncons containing the types of the general constraints:
_GENCONS_MAX (0)
indicates a maximum constraint;
_GENCONS_MIN (1)
indicates a minimum constraint;
_GENCONS_AND (2)
indicates an and constraint.
_GENCONS_OR (3)
indicates an or constraint;
_GENCONS_ABS (4)
indicates an absolute value constraint.
resultant 
Integer array of length ncons containing the indices of the output variables of the general constraints.
colstart 
Integer array of length ncons containing the start index of each general constraint in the colind array.
colind 
Integer array of length ncols containing the input variables in all general constraints.
valstart 
Integer array of length ncons containing the start index of each general constraint in the val array (may be NULL if ncoefs = 0).
val 
Double array of length nvals containing the constant values in all general constraints (may be NULL if ncoefs = 0).
ncons 
The number of general constraints to add.
ncols 
The total number of input variables in general constraints that should be added.
nvals 
The total number of constant values in general constraints that should be added.
Return value
The input argument prob.
