Perhaps you should try some spelling variations:
"pose estimation algorithms" » "pose estimation algorithm", "pose optimization algorithms", "pose optimisation algorithm"
"_ simulation algorithm" » "_ estimation algorithm", "_ solution algorithm", "_ optimisation algorithm"
"3d simulation algorithm" » "3d estimation algorithm", "3d solution algorithm", "3d optimisation algorithm", "a simulation algorithm", "mri simulation algorithm", "via simulation 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: (((("_ simulation algorithm") or ("3d simulation algorithm"))) or ("pose estimation algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("_ simulation algorithm") OR ("3d simulation algorithm"))) OR ("pose estimation algorithms")).
• Removing quotes may allow a broader search: (((( _ simulation algorithm ) or ( 3d simulation algorithm ))) or ( pose estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (((("_ simulation algorithm") or ("3d simulation algorithm"))) or ("pose estimation algorithms"))*.
