When i tried to optimise LQR controller using Genetic Algorithm toolbox i got the result as " Optimization terminated: average change in the fitness value less than options.TolFun." What does it mean?

It means that the relative change in the fitness value between iterations is less than the value you set for 'TolFun'. If the fitness value does not change significantly between iterations, the genetic algorithm assumes that it has converged on an appropriate set of parameter estimates.
