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 quadratic optimization algorithm" » "modified static optimization algorithm", "modified quadratic optimisation algorithm", "modified quadratic estimation algorithm", "modified quadratic estimation algorithms"

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