Perhaps you should try some spelling variations:
"_ optimised algorithms" » "_ optimized algorithms", "_ optimized algorithm", "_ optimizer algorithms"
"_ optimize algorithmss" » "_ optimized algorithms", "_ optimizer algorithms", "_ optimized algorithm", "_ optimized algorithmss", "_ optimise algorithmss"
"risk estimation algorithm" » "pose estimation algorithm"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((("_ optimised algorithms") or ("_ optimize algorithmss"))) or ("risk estimation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("_ optimised algorithms") OR ("_ optimize algorithmss"))) OR ("risk estimation algorithm")).
• Removing quotes may allow a broader search: (((( _ optimised algorithms ) or ( _ optimize algorithmss ))) or ( risk estimation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("_ optimised algorithms") or ("_ optimize algorithmss"))) or ("risk estimation algorithm"))*.
