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