Hi All
when i using Rapidminer for optimization a problems, its run for some time faster and then slowly and finally stopped without complete all generation that i wanted. therefor the problem didn't optimized, and the performance very bad.
any help???
my PC specification
RAM:32G
CPU: i7-3820

we have to admit the the Parallel extension sometimes has some hickups and needs a major revamp. Please try to run your process without the parallelization features.
Furthermore you are using an evolutionary parameter optimization for an SVM. For some parameter settings the SVM becomes very slow (e.g. large C). With the evolutionary optimization you have no control over the parameter values, which means that "slow" parameters could be introduced and probably survive for some generations. In that case your process could become very slow. So in case of the SVM you should consider to you Optimize Parameters (Grid) instead of the evolutionary variant.
