Perhaps you should try some spelling variations:
"_ optimization algorithms" » "_ optimisation algorithm", "_ estimation algorithms", "_ optimized algorithms"
"a solution algorithm" » "a evolution algorithm", "a convolution algorithms", "a evolutionary algorithm", "_ solution algorithm", "_ solutions algorithm", "nacl solution algorithm"
"policy estimation algorithm" » "policy optimization algorithm", "pose estimation algorithm", "motion estimation algorithm"

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: (((("a solution algorithm") or ("_ optimization algorithms"))) or ("policy estimation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("a solution algorithm") OR ("_ optimization algorithms"))) OR ("policy estimation algorithm")).
• Removing quotes may allow a broader search: (((( a solution algorithm ) or ( _ optimization algorithms ))) or ( policy estimation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("a solution algorithm") or ("_ optimization algorithms"))) or ("policy estimation algorithm"))*.
