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