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

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"_ optimisation algorithm\") OR (\"_ optimized algorithmsss\"))) OR (\"same optimized algorithm\"))~".
• Removing quotes may allow a broader search: (((( _ optimisation algorithm ) OR ( _ optimized algorithmsss ))) OR ( same optimized algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("_ optimisation algorithm") OR ("_ optimized algorithmsss"))) OR ("same optimized algorithm"))*.
