How can i find the optimal switching sequence using a cost function.

I have a matlab function block whose inputs are switching sequences at the rate of 1 switching sequence per microsecond. The script in the function block have a cost function. All i need is to find the min cost function for 4 sampling intervals ie 4 microseconds i.e. 4 switching sequence and the output should be the optimal switching sequence out of the 4 sequences and this optimal sequence should be generated for every 4 microseconds. Can anyone help me with this. Thanks

Hello

You reported an optimization problem if i'm right (Minimizing a cost function).

The main idea is to implement an algorithm (PSO, GA,...) that will run your program succesively for different sets of parameters (here your switching sequences) and compute their cost equivalent function until it finds the best set.
