Update problem data on a persistent Clarabel solver

Source: R/clarabel.R
solver_update.Rd

Update one or more of P (objective), q (linear objective), A (constraints), b (constraint RHS) on an existing solver. The sparsity pattern of P and A must remain the same as the original problem; only the nonzero values can change.

Usage

solver_update(solver, P = NULL, q = NULL, A = NULL, b = NULL)

Arguments

solver

a ClarabelSolver object created by clarabel_solver()

P

new upper-triangular P matrix (same sparsity), or NULL to leave unchanged

q

new linear objective vector, or NULL to leave unchanged

A

new constraint matrix (same sparsity), or NULL to leave unchanged

b

new constraint RHS vector, or NULL to leave unchanged

Value

invisible NULL

Examples

if (FALSE) { # \dontrun{
solver_update(s, q = c(-4, -1))   # update linear objective only
solver_update(s, b = c(2, 2))     # update constraint RHS only
sol2 <- solver_solve(s)           # re-solve with updated data
} # }
