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.
