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