MathOptNLPModel(model, hessian=true, name="Generic")

Construct a MathOptNLPModel from a JuMP model.

hessian should be set to false for multivariate user-defined functions registered without hessian.

MathOptNLSModel(model, F, hessian=true, name="Generic")

Construct a MathOptNLSModel from a JuMP model and a container of JuMP GenericAffExpr (generated by @expression) and NonlinearExpression (generated by @NLexpression).

hessian should be set to false for multivariate user-defined functions registered without hessian.

add_constraint_model(Fmodel, Fi)

Add the nonlinear constraint Fi == 0 to the model Fmodel. If Fi is an Array, then we iterate over each component.

coo_sym_add_mul!(rows, cols, vals, x, y, α)

Perform the update y ← y + α * A * x where A is a symmetric matrix in COO format given by (rows, cols, vals). Only one triangle of A should be passed.

coo_sym_dot(rows, cols, vals, x, y)

Compute the product xᵀAy of a symmetric matrix A given by (rows, cols, vals). Only one triangle of A should be passed.

coo_unsym_add_mul!(transpose, rows, cols, vals, x, y, α)

Performs the update y ← y + α * op(A) * x, where A is an unsymmetric matrix in COO format given by (rows, cols, vals). If transpose == true, then op(A) = Aᵀ; otherwise, op(A) = A.
