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