Solves an optimization model using GLPK solver (glpkAPI or glpsol)
Usage
solve_gmpl(
model = NULL,
model_dir,
method = "glpkAPI",
verbose = TRUE,
load_results = !is.null(model),
glpsol_path = "glpsol",
timeout = NULL
)Arguments
- model
Optional model object (for loading results back)
- model_dir
Directory containing model files (model.mod, data.dat, etc.)
- method
Solver method: "glpkAPI" (default, uses execute_glpkAPI), "glpsol" (uses system2 with glpsol executable)
- verbose
Logical; print progress messages (default: TRUE)
- load_results
Logical; load solution CSV results back into model object (default: !is.null(model))
- glpsol_path
Path to glpsol executable (default: "glpsol", only used if method="glpsol")
- timeout
Numeric; timeout in seconds (default: NULL, no timeout)
