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