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