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