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