Add a quadratic constraint to a SCIP model

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

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.
