Perhaps you should try some spelling variations:
"modified bi1 optimization algorithm" » "modified bi1 optimization algorithms", "modified bi1 estimation algorithm", "modified bi1 estimation algorithms", "modified _ optimization algorithm", "modified qoe optimization algorithm", "modified game optimization algorithm"
"modified objective optimisation algorithm" » "modified objective optimization algorithm", "modified multiobjective optimization algorithm", "modified objective optimization algorithms", "modified objective estimation algorithm", "modified objective estimation algorithms"

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 algorithm") or ("modified objective optimisation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified bi1 optimization algorithm") OR ("modified objective optimisation algorithm")).
• Removing quotes may allow a broader search: (( modified bi1 optimization algorithm ) or ( modified objective optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified bi1 optimization algorithm") or ("modified objective optimisation algorithm"))*.
