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