Perhaps you should try some spelling variations:
"risk estimation algorithms" » "risk estimation algorithm", "risk optimization algorithms", "risk optimisation algorithm", "pose estimation algorithms"
"cong optimized algorithm" » "cong optimized algorithms", "cong optimizer algorithms"
"one optimized algorithm" » "one optimized algorithms", "one optimizer algorithms", "_ optimized algorithm"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((("cong optimized algorithm") OR ("one optimized algorithm"))) OR ("risk estimation algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"cong optimized algorithm\") OR (\"one optimized algorithm\"))) OR (\"risk estimation algorithms\"))".
• Removing quotes may allow a broader search: (((( cong optimized algorithm ) OR ( one optimized algorithm ))) OR ( risk estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (((("cong optimized algorithm") OR ("one optimized algorithm"))) OR ("risk estimation algorithms"))*.
