problem.delConstraint

Purpose
Delete one or more constraints from the problem.
Synopsis
problem.delConstraint(constraints)
Example 
N = 20
p = xpress.problem()
x = [p.addVariable() for i in range(N)]
p.addConstraint(x[i] >= x[i+1] for i in range(N-1))
p.delConstraint(2) # deletes x[2] >= x[3]
Further information
1. The argument can be a single constraint or a list, tuple or NumPy array of constraints. Instead of constraint objects, indices can also be used (from 0 to ROWS-1). The index of a constraint can be obtained with problem.getIndex.
2. Indicator constraints are indexed as constraints, hence they can also be deleted with this function.
