[R] R interface to PSwarm

[Hans W Borchers]

Dear list:

Being a bit unsatisfied with global optimization approaches in R such as "SANN"
(in 'optim') or DEoptim, I looked for alternatives on the Web, such as PSwarm
<http://www.norg.uminho.pt/aivaz/pswarm/> or PIKAIA.

There is an R interface to PSwarm (version 1.4) on its home page which I was not
able to make run under Windows, getting the error message

"Error: SET_VECTOR_ELT() can only be applied to a 'list', not a 'character'"

when running the example.

Therefore my questions:

  - Has someone successfully tried out PSwarm with R ? 

  - Are there any experiences with PSwarm in general, that is could you find
solutions with PSwarm that you did not find with another GA or with Rdonlp2, for
example ?
