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

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 algorithm") or ((("_ optimization algorithm") OR ("_ optimisation algorithm"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("same optimized algorithm") OR ((("_ optimization algorithm") OR ("_ optimisation algorithm")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"same optimized algorithm\") or (((\"_ optimization algorithm\") OR (\"_ optimisation algorithm\"))))".
• Removing quotes may allow a broader search: (( same optimized algorithm ) or ((( _ optimization algorithm ) OR ( _ optimisation algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("same optimized algorithm") or ((("_ optimization algorithm") OR ("_ optimisation algorithm"))))*.
