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