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

Try widening your search to All Fields.

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

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