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

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