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