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