The High Throughput MultiSolution Genetic Algorithm (HTMGA) is a Matlab toolbox that finds multiple solutions in an objective function.  In deterministic model updating this is equivalent to finding several set of parameters that are a likely representation of the experimental results.  In probabilistic model updating this tool can be used to find the regions of high probability.  HTMGA can be used in a single computer or through high throughput strategies such as Condor.
