Perhaps you should try some spelling variations:
"modified bi1 optimization algorithmss" » "modified bi1 optimization algorithms", "modified bi1 optimisation algorithm", "modified bi1 estimation algorithms", "modified bi1 optimization algorithmsss", "modified bi1 optimisation algorithmss", "modified bi1 estimation algorithmss", "modified _ optimization algorithmss", "modified qoe optimization algorithmss", "modified game 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 bi1 optimization algorithmss") or ("modified multiobjective optimization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified bi1 optimization algorithmss") OR ("modified multiobjective optimization algorithm")).
• Removing quotes may allow a broader search: (( modified bi1 optimization algorithmss ) or ( modified multiobjective optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified bi1 optimization algorithmss") or ("modified multiobjective optimization algorithm"))*.
