Perhaps you should try some spelling variations:
"same optimisation algorithm" » "same optimization algorithms", "same estimation algorithms", "game optimization algorithm", "stage optimization algorithm", "_ optimisation algorithm"
"_ optimized algorithm" » "_ optimized algorithms", "_ optimizer algorithms"
"same estimation algorithm" » "pose estimation algorithm", "sphere estimation algorithm"

Try widening your search to All Fields.

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 ((("same optimisation algorithm") OR ("same estimation algorithm"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("_ optimized algorithm") OR ((("same optimisation algorithm") OR ("same estimation algorithm")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"_ optimized algorithm\") or (((\"same optimisation algorithm\") OR (\"same estimation algorithm\"))))".
• Removing quotes may allow a broader search: (( _ optimized algorithm ) or ((( same optimisation algorithm ) OR ( same estimation algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("_ optimized algorithm") or ((("same optimisation algorithm") OR ("same estimation algorithm"))))*.
