Perhaps you should try some spelling variations:
"_ optimisation algorithm" » "_ optimization algorithms", "_ estimation algorithm", "_ estimation algorithms", "_ optimization algorithm"
"post optimized algorithm" » "post optimized algorithms", "post optimizer algorithms", "cost optimized algorithm"
"most optimized algorithm" » "most optimized algorithms", "most optimizer algorithms"

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