Perhaps you should try some spelling variations:
"_ simulation algorithm" » "_ solution algorithm", "_ optimisation algorithm", "_ estimation algorithms"
"policy estimation algorithm" » "policy optimization algorithm", "pose estimation algorithm", "motion estimation algorithm"
"_ splitting algorithm" » "_ pitting algorithm", "_ splicing algorithm"

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

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