problem.delConstraint
problem.delConstraint |
Purpose
Delete one or more constraints from the problem.
Synopsis
problem.delConstraint(c1, c2, ...)
Example
N = 20 x = [xpress.var() for i in range(N)] p = xpress.problem() p.addVariable(x) p.addConstraint(x[i] >= x[i+1] for i in range(N-1)) p.delConstraint(2) # deletes x[2] >= x[3]
Further information
1. All arguments can be single constraints or lists, tuples, or NumPy arrays of variables. They can also be constraint indices (from 0 to
ROWS-1). The index of variables, constraints, and SOSs can be obtained with
problem.getIndex.
2. Indicator constraints are indexed as constraints, hence they can also be deleted with this function.
