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