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