Perhaps you should try some spelling variations:
"_ optimization algorithms" » "_ optimisation algorithm", "_ estimation algorithms", "_ estimation algorithm"
"one optimized algorithms" » "one optimized algorithm", "one optimizer algorithms", "_ optimized algorithms"
"_ optimize algorithms" » "_ optimizer algorithms", "_ optimized algorithm"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("_ optimize algorithms") or ("one optimized algorithms"))) or ("_ optimization algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("_ optimize algorithms") OR ("one optimized algorithms"))) OR ("_ optimization algorithms")).
• Removing quotes may allow a broader search: (((( _ optimize algorithms ) or ( one optimized algorithms ))) or ( _ optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (((("_ optimize algorithms") or ("one optimized algorithms"))) or ("_ optimization algorithms"))*.
