Perhaps you should try some spelling variations:
"modified make optimization algorithmss" » "modified make optimization algorithms", "modified make optimisation algorithm", "modified make estimation algorithms", "modified make optimization algorithmsss", "modified make optimisation algorithmss", "modified make estimation algorithmss", "modified market optimization algorithmss", "modified game optimization algorithmss", "modified stage optimization algorithmss", "modified male optimization algorithmss"
"modified multiobjective optimization algorithm" » "modified multiobjective optimization algorithms", "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithm"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified make optimization algorithmss") or ("modified multiobjective optimization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified make optimization algorithmss") OR ("modified multiobjective optimization algorithm")).
• Removing quotes may allow a broader search: (( modified make optimization algorithmss ) or ( modified multiobjective optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified make optimization algorithmss") or ("modified multiobjective optimization algorithm"))*.
