hi_solver_change_constraint_bounds: Change Constraint Bounds

In highs: 'HiGHS' Optimization Solver

Change Constraint Bounds

Description

This function updates the bounds of an existing constraint in the model.

Usage

hi_solver_change_constraint_bounds(solver, idx, lhs, rhs)

Arguments

solver	An object of class "highs_solver".
idx	An integer vector specifying the constraint indices. Note that idx starts at 0.
lhs	The new left-hand side bound.
rhs	The new right-hand side bound.

Details

This is a low-level wrapper for 'highs.changeRowsBounds' that only does basic checks to prevent segfaults, but otherwise behaves exactly like 'highs.changeRowsBounds'.

Value

The solver instance with updated constraint bounds.

Examples

solver <- example_solver()
hi_solver_change_constraint_bounds(solver, 1, -Inf, 100)
