Perhaps you should try some spelling variations:
"_ optimisation algorithm" » "_ optimization algorithms", "_ estimation algorithms", "_ optimization algorithm"
"_ optimize algorithms" » "_ optimized algorithms", "_ optimizer algorithms", "_ optimized algorithm", "_ optimise algorithms"
"qoe estimation algorithm" » "pose estimation algorithm", "_ estimation algorithm", "cover estimations algorithm"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"qoe estimation algorithm\") OR (\"_ optimize algorithms\"))) OR (\"_ optimisation algorithm\"))~".
• Removing quotes may allow a broader search: (((( qoe estimation algorithm ) OR ( _ optimize algorithms ))) OR ( _ optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("qoe estimation algorithm") OR ("_ optimize algorithms"))) OR ("_ optimisation algorithm"))*.
