Perhaps you should try some spelling variations:
"modified objective optimization algorithms" » "modified objective optimisation algorithm", "modified objective estimation algorithms", "modified objective estimation algorithm", "modified multiobjective optimization 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 time solutions algorithm") or ("modified objective optimization algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified time solutions algorithm") OR ("modified objective optimization algorithms")).
• Removing quotes may allow a broader search: (( modified time solutions algorithm ) or ( modified objective optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified time solutions algorithm") or ("modified objective optimization algorithms"))*.
