Perhaps you should try some spelling variations:
"_ optimisation algorithm" » "_ optimization algorithms", "_ estimation algorithm", "_ estimation algorithms", "_ optimization algorithm"
"_ optimized algorithms" » "_ optimized algorithm", "_ optimization algorithms"
"same optimizer algorithms" » "same optimized algorithm", "same optimization 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: (((("_ optimized algorithms") OR ("_ optimisation algorithm"))) OR ("same optimizer algorithms"))~.
• Removing quotes may allow a broader search: (((( _ optimized algorithms ) or ( _ optimisation algorithm ))) or ( same optimizer algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (((("_ optimized algorithms") or ("_ optimisation algorithm"))) or ("same optimizer algorithms"))*.
