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