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

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (((("_ optimisation algorithm") OR ("_ optimise algorithms"))) OR ("cover estimation algorithm"))~.
• Removing quotes may allow a broader search: (((( _ optimisation algorithm ) or ( _ optimise algorithms ))) or ( cover estimation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("_ optimisation algorithm") or ("_ optimise algorithms"))) or ("cover estimation algorithm"))*.
