Perhaps you should try some spelling variations:
"_ optimiser algorithms" » "_ optimizer algorithms", "_ optimized algorithms", "_ optimized algorithm", "_ optimize algorithms", "_ optimizedr algorithms"
"_ optimise algorithm" » "_ optimized algorithm", "_ optimized algorithms", "_ optimizer algorithms", "_ optimize algorithm"
"notion estimation algorithm" » "motion 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: (("notion estimation algorithm") OR ((("_ optimise algorithm") OR ("_ optimiser algorithms"))))~.
• Removing quotes may allow a broader search: (( notion estimation algorithm ) or ((( _ optimise algorithm ) or ( _ optimiser algorithms ))))~.
• Adding a wildcard symbol may retrieve word variants: (("notion estimation algorithm") or ((("_ optimise algorithm") or ("_ optimiser algorithms"))))*.
