Perhaps you should try some spelling variations:
"a estimation algorithms" » "a optimization algorithms", "a optimisation algorithm", "a approximation algorithms", "_ estimation algorithms", "a destination algorithms", "_ estimating algorithms"
"a simulation algorithm" » "a solution algorithm", "a optimisation algorithm", "a evolution algorithm", "_ simulation algorithm"
"motion estimation algorithm" » "notion estimation algorithm"

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

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