Perhaps you should try some spelling variations:
"modified multiobjective optimisation algorithm" » "modified multiobjective optimization algorithm", "modified objective optimization algorithm", "modified multiobjective optimization algorithms", "modified multiobjective estimation algorithm", "modified multiobjective estimation algorithms"
"modified time solutions algorithm" » "modified time solution algorithm", "modified time evolution algorithm", "modified time evolutionary algorithm", "modified mild solutions algorithm", "modified bi1 solutions algorithm", "modified male solutions algorithm"

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