solnp_problems_table: List of Valid Test Problems for the SOLNP Suite

In Rsolnp: General Non-Linear Optimization

List of Valid Test Problems for the SOLNP Suite

Description

Returns a data.frame of known and registered test problems used with the SOLNP solver. The list includes problems from the Hock-Schittkowski suite as well as a selection of other classic optimization problems.

Usage

solnp_problems_table()

Details

• All problem functions are expected to follow the naming convention ‘Problem_problem’ (e.g., ‘hs01_problem’).

• For Hock-Schittkowski problems, numbers range from 1 to 50, with a few selected extras (e.g., 110, 118, 119).

• The “Other” suite includes named problems like ‘box’, ‘alkylation’, ‘entropy’, ‘garch’, etc., and are numbered sequentially.

Value

A data.frame with the following columns:

Suite

A character string indicating the suite the problem belongs to. One of “Hock-Schittkowski” or “Other”.

Problem

The base name of the problem function (without the ‘_problem’ suffix).

Number

An integer identifier used to index or request problems programmatically.

# View all known problems
tail(solnp_problems_table())

# Filter only HS problems
head(subset(solnp_problems_table(), Suite == "Hock-Schittkowski"))
