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

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

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