Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
objective optimization » multiobjective optimization
evolution algorithm » solution algorithm, evolutionary algorithm, convolution algorithms
modified passive » modified adaptive

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 objective optimization algorithms ) OR ( modified passive evolution algorithm ))~".
• Adding a wildcard symbol may retrieve word variants: (( modified objective optimization algorithms ) OR ( modified passive evolution algorithm ))*.
