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

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