Perhaps you should try some spelling variations:
parameters optimization » parameter optimization, parameter estimation
evolutionary algorithm » evolution algorithm, solution algorithm
optimization algorithm » optimization algorithms, optimisation algorithm, estimation algorithm
modified up » modified _, modified df, modified bi1

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( modified up evolutionary algorithm ) OR ( modified parameters optimization algorithm ))~".
• Adding a wildcard symbol may retrieve word variants: (( modified up evolutionary algorithm ) OR ( modified parameters optimization algorithm ))*.
