[jira] [Updated] (MATH-1108) SimplexSolver returns
TooManyIterationsException
[ https://issues.apache.org/jira/browse/MATH-1108?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Thomas Neidhart updated MATH-1108:
----------------------------------
Issue Type: Improvement (was: Bug)
> SimplexSolver returns TooManyIterationsException
> ------------------------------------------------
>
> Key: MATH-1108
> URL: https://issues.apache.org/jira/browse/MATH-1108
> Project: Commons Math
> Issue Type: Improvement
> Affects Versions: 3.2, 3.1.1
> Reporter: Buharov Alexander
> Fix For: 4.0
>
> Attachments: AdipocyteModel.xml, Problem.zip
>
>
> We have vector v and matrix s (from file S.txt)
> v - vector ( size: 1*649 )
> s - matrix ( size: 554*649 )
> We want solve linear problem:
> * max (v[31])
> * Bounds:
> * s*v = 0
> * -1 <= v[i] <= 1 for i=0,..., 648
> We changed MaxIter parameter (from 100 to 1e+6). And we changed epsilon ( set default value and 1e-3). But solver always throws TooManyIterationsException (and work very slow).
