Perhaps you should try some spelling variations:
"post estimation algorithms" » "post estimation algorithm", "post optimization algorithms", "post optimisation algorithm", "pose estimation algorithms", "risk estimation algorithms", "pulses estimation algorithms"
"via simulation algorithm" » "via estimation algorithm", "via solution algorithm", "via optimisation algorithm", "a simulation algorithm", "_ simulation algorithm", "mri simulation algorithm"
"3d simulation algorithm" » "3d estimation algorithm", "3d solution algorithm", "3d optimisation algorithm", "_ simulation algorithm", "a simulation algorithm", "mri simulation algorithm"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("post estimation algorithms") or ((("via simulation algorithm") OR ("3d simulation algorithm"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("post estimation algorithms") OR ((("via simulation algorithm") OR ("3d simulation algorithm")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"post estimation algorithms\") or (((\"via simulation algorithm\") OR (\"3d simulation algorithm\"))))".
• Removing quotes may allow a broader search: (( post estimation algorithms ) or ((( via simulation algorithm ) OR ( 3d simulation algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("post estimation algorithms") or ((("via simulation algorithm") OR ("3d simulation algorithm"))))*.
