Perhaps you should try some spelling variations:
"modified stochastic optimization algorithm" » "modified stochastic optimization algorithms", "modified stochastic optimisation algorithm", "modified stochastic estimation algorithm"
"modified motion optimized algorithm" » "modified motion optimized algorithms", "modified motion optimizer algorithms", "modified notion optimized 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 motion optimized algorithm\") OR (\"modified stochastic optimization algorithm\"))~".
• Removing quotes may allow a broader search: (( modified motion optimized algorithm ) OR ( modified stochastic optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified motion optimized algorithm") OR ("modified stochastic optimization algorithm"))*.
