Perhaps you should try some spelling variations:
"modified notion estimation algorithms" » "modified notion estimation algorithm", "modified notion optimization algorithms", "modified notion optimisation algorithm", "modified motion estimation algorithms"
"machinery learning method algorithm" » "machine learning method algorithm", "machinery learning mom algorithm", "machinery learning methods algorithm", "machinery graining methods algorithm", "machinery learning emotion algorithm"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"machinery learning method algorithm\") OR (\"modified notion estimation algorithms\"))~".
• Removing quotes may allow a broader search: (( machinery learning method algorithm ) OR ( modified notion estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("machinery learning method algorithm") OR ("modified notion estimation algorithms"))*.
