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