Description Usage Arguments Details Value Author(s) References Examples

The function implements a set of benchmark problems against the MINOS solver of Murtagh and Saunders.

1	benchmark(id = "Powell")

`id`	The name of the benchmark problem. A call to the function `benchmarkids` will return the available benchmark problems.

The benchmarks were run on dual xeon server with 24GB of memory and windows 7 operating system. The MINOS solver was used via the tomlab interface.

A data.frame containing the benchmark data. The description of the benchmark problem can be accessed throught the description attribute of the data.frame.
