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