Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithms" » "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithms", "modified multiobjective estimation algorithm"
"modified based solutions algorithm" » "modified based solution algorithm", "modified based evolution algorithm", "modified based evolutionary algorithm", "modified male solutions algorithm"

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 based solutions algorithm") or ("modified multiobjective optimization algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified based solutions algorithm") OR ("modified multiobjective optimization algorithms")).
• Removing quotes may allow a broader search: (( modified based solutions algorithm ) or ( modified multiobjective optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified based solutions algorithm") or ("modified multiobjective optimization algorithms"))*.
