scip_add_quadratic_cons: Add a quadratic constraint to a SCIP model

In scip: Interface to the SCIP Optimization Suite

Add a quadratic constraint to a SCIP model

Description

Adds lhs <= linexpr + quadexpr <= rhs where quadexpr = sum(quadcoefs[k] * x[quadvars1[k]] * x[quadvars2[k]]).

Usage

scip_add_quadratic_cons(
  model,
  linvars = integer(0),
  lincoefs = double(0),
  quadvars1 = integer(0),
  quadvars2 = integer(0),
  quadcoefs = double(0),
  lhs = -Inf,
  rhs = Inf,
  name = NULL
)

Arguments

model	A SCIP model.
linvars	Integer vector; 1-based variable indices for linear part.
lincoefs	Numeric vector; linear coefficients.
quadvars1, quadvars2	Integer vectors; 1-based variable indices for quadratic terms.
quadcoefs	Numeric vector; quadratic coefficients.
lhs, rhs	Numeric; constraint bounds.
name	Character; constraint name.

Value

Integer; 1-based constraint index.
