Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
objective optimization » multiobjective optimization
evolutionary algorithm » evolution algorithm, solution algorithm
modified deep » modified delphi, modified df, modified near

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

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