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