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