Perhaps you should try some spelling variations:
"pose estimation algorithms" » "pose estimation algorithm", "pose optimization algorithms", "pose optimisation algorithm", "poses estimation algorithms", "post estimation algorithms", "jose estimation algorithms"
"exact solution algorithm" » "exact evolution algorithm", "exact convolution algorithms", "exact evolutionary algorithm"
"nacl solution algorithm" » "nacl evolution algorithm", "nacl convolution algorithms", "nacl evolutionary algorithm", "nodal solution 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: (("pose estimation algorithms") or ((("exact solution algorithm") OR ("nacl solution algorithm"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("pose estimation algorithms") OR ((("exact solution algorithm") OR ("nacl solution algorithm")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"pose estimation algorithms\") or (((\"exact solution algorithm\") OR (\"nacl solution algorithm\"))))".
• Removing quotes may allow a broader search: (( pose estimation algorithms ) or ((( exact solution algorithm ) OR ( nacl solution algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("pose estimation algorithms") or ((("exact solution algorithm") OR ("nacl solution algorithm"))))*.
