PANMIN
Sequential and parallel global optimization procedures
with a variety of options for the local search strategy
PANMIN is a suite of programs for global optimization that take advantage of the
Merlin/MCL environment.
Specificaly PANMIN contains implementations of two algorithms that
belong to the stochastic class.
The first one is a modification of the "Controlled Random Search" (CRS)
originally introduced by Price
(W. L. Price in Toward Global Optimization 2, L.C.W. Dixon and G.P.Szego eds.),
and aims to locate only one global minimum.
The second one is the "Healed Topographical Multilevel Single Linkage"
(HTMLSL) that is based on the Multi Level Single Linkage method of
Kan and Timmer
(Math. Prog. 39, 1987, 27,
Math. Prog. 39, 1987, 57,
Ph.D. Thesis, Erasmus University Rotterdam),
with topographical modifications inspired from the articles by Ali and Storey
(J. Glob. Opt. 5, 1994, 349)
and by Törn and Viitanen (J. Glob. Opt. 5, 1994, 267).
The above two codes are sequential and do not take advantage of environments
with multiple processors. Note that CRS can hardly benefit from such
a computational environment due to the nature of its algorithmic structure.
HTMLSL lends itself to parallel processing and PANMIN contains a parallel
implementation of the algorithm that uses
the Message Passing Interface (MPI) to take advantage of either a shared memory
architecture or a distributed environment with interconnected computers.
PANMIN is described in the following article:
