Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithms" » "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithms", "modified multiobjective estimation algorithm"
"modified d solution algorithm" » "modified d evolution algorithm", "modified d convolution algorithms", "modified d evolutionary algorithm", "modified df solution algorithm", "modified _ solution algorithm", "modified adam solution algorithm", "modified _ solutions algorithm", "modified drug solution 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 d solution algorithm\"))~".
• Removing quotes may allow a broader search: (( modified multiobjective optimization algorithms ) OR ( modified d solution algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimization algorithms") OR ("modified d solution algorithm"))*.
