"Combinatorial optimization algorithms are often implemented in an efficient imperative programming language, in an expressive declarative programming language such as Prolog, or some compromise, perhaps a functional programming language such as Haskell, or a multi-paradigm language such as LISP." - What it actually says: "Combinatorial optimization algorithms are usually implemented in some kind of programming language." -What's the point?

constantin

I found the listing of programs and their classifications helpful and useful.

mrxe

agree with constantin; that paragraph says nothing

tom

I also agree with constantin, and I think that information about implementation would be better located towards the end of the article, as seems to be the style for most algorithm articles in Wikipedia. Davidcoffin 09:44, 18 January 2007 (UTC)[reply]

Metropolis and Hill-Climbing Cross References Needed

Besides mention of simulating annealing, the Metropolis algorithm (to be found in Wikipedia, not by "Metropolis" but by "Metropolis-Hastings") should very definitely be referenced or cross-referenced here. More generally, Hill-Climbing should be referenced. And in Hill-Climbing entry, I don't see "probabilistic hill-climbing".
Probabilistic hill-climbing is a counter-intuitive notion. Well, after a while (like when everybody see a unicorn -- so what), the notion seems less counter-intuitive, but in each step you have some chance (probability) of going towards a "worse" configuration -- and in that way you (most likely) avoid getting stuck in local optimum as opposed to global optimum. This central notion should be part of combinatorial optimization entry.199.196.144.11 19:34, 21 March 2007 (UTC)[reply]

Add: Agree. This is an important aspect of combinatorial optimization as it is how most real-world applications solve it. In the "Distributed Combinatorial Section," a probabilistic hill-climbing algorithm is cited.
