Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithms" » "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithms", "modified multiobjective estimation algorithm"
"modified make evolution algorithm" » "modified make solution algorithm", "modified make evolutionary algorithm", "modified make convolution algorithms", "modified sales evolution algorithm", "modified time evolution algorithm", "modified male evolution algorithm"

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 multiobjective optimization algorithms\") OR (\"modified make evolution algorithm\"))~".
• Removing quotes may allow a broader search: (( modified multiobjective optimization algorithms ) OR ( modified make evolution algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimization algorithms") OR ("modified make evolution algorithm"))*.
