Perhaps you should try some spelling variations:
"modified multiobjective estimation algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective estimation algorithm", "modified multiobjective optimisation algorithm"
"modified adam solutions algorithms" » "modified adam solution algorithm", "modified adam evolution algorithm", "modified adam convolution algorithms", "modified df solutions algorithms", "modified near solutions algorithms"

Try widening your search to All Fields.

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified multiobjective estimation algorithms") or ("modified adam solutions algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified multiobjective estimation algorithms") OR ("modified adam solutions algorithms")).
• Removing quotes may allow a broader search: (( modified multiobjective estimation algorithms ) or ( modified adam solutions algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective estimation algorithms") or ("modified adam solutions algorithms"))*.
