Perhaps you should try some spelling variations:
"modified objective optimization algorithm" » "modified multiobjective optimization algorithm", "modified objective optimization algorithms", "modified objective optimisation algorithm", "modified objective estimation algorithm"
"modified optimal optimizer algorithms" » "modified optimal optimized algorithms", "modified optimal optimized algorithm", "modified optimal optimization algorithms", "modified thermal optimizer algorithms"

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