Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
evolutionary algorithm » evolution algorithm, solution algorithm
objective optimization » multiobjective optimization
modified mild » modified male, modified seird, modified bi1

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( modified mild evolutionary algorithm ) OR ( modified objective optimization algorithms ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( modified mild evolutionary algorithm ) OR ( modified objective optimization algorithms ))".
• Adding a wildcard symbol may retrieve word variants: (( modified mild evolutionary algorithm ) OR ( modified objective optimization algorithms ))*.
