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

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

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