Perhaps you should try some spelling variations:
"modified stochastic estimation algorithms" » "modified stochastic optimization algorithms", "modified stochastic estimation algorithm", "modified stochastic optimisation algorithm"
"modified learning method algorithm" » "mobile learning method algorithm", "modified caging method algorithm", "modified learning mom algorithm", "modified learning methods algorithm", "modified graining methods algorithm", "modified 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: "((\"modified learning method algorithm\") OR (\"modified stochastic estimation algorithms\"))~".
• Removing quotes may allow a broader search: (( modified learning method algorithm ) OR ( modified stochastic estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified learning method algorithm") OR ("modified stochastic estimation algorithms"))*.
