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