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