Perhaps you should try some spelling variations:
"don optimizer algorithms" » "don optimized algorithms", "don optimization algorithms", "dong optimizer algorithms", "doan optimizer algorithms"
"jose optimized algorithm" » "jose optimized algorithms"
"game estimation algorithm" » "pose estimation algorithm", "game optimization algorithm"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("don optimizer algorithms") or ("jose optimized algorithm"))) or ("game estimation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("don optimizer algorithms") OR ("jose optimized algorithm"))) OR ("game estimation algorithm")).
• Removing quotes may allow a broader search: (((( don optimizer algorithms ) or ( jose optimized algorithm ))) or ( game estimation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("don optimizer algorithms") or ("jose optimized algorithm"))) or ("game estimation algorithm"))*.
