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