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