Perhaps you should try some spelling variations:
"don optimization algorithms" » "don optimisation algorithm", "don estimation algorithms", "don optimized algorithms", "qoe optimization algorithms", "_ optimization algorithms", "game optimization algorithms"
"_ optimized algorithm" » "_ optimized algorithms", "_ optimizer algorithms"
"post estimation algorithm" » "pose estimation algorithm", "risk estimation algorithm", "pulses estimation algorithm"

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

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