Perhaps you should try some spelling variations:
"modified bi1 optimization algorithmssss" » "modified bi1 optimization algorithms", "modified _ optimization algorithmssss", "modified qoe optimization algorithmssss", "modified game optimization algorithmssss"
"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 algorithmssss") OR ("modified objective optimisation algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified bi1 optimization algorithmssss\") OR (\"modified objective optimisation algorithm\"))".
• Removing quotes may allow a broader search: (( modified bi1 optimization algorithmssss ) OR ( modified objective optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified bi1 optimization algorithmssss") OR ("modified objective optimisation algorithm"))*.
