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