Perhaps you should try some spelling variations:
"modified stochastic optimization algorithms" » "modified stochastic optimisation algorithm", "modified stochastic estimation algorithms", "modified stochastic estimation algorithm"
"modified graining methods algorithm" » "modified caging methods algorithm", "modified learning methods algorithm", "modified learning method algorithm", "modified making methods algorithm"

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified stochastic optimization algorithms") OR ("modified graining methods algorithm"))~.
• Removing quotes may allow a broader search: (( modified stochastic optimization algorithms ) or ( modified graining methods algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified stochastic optimization algorithms") or ("modified graining methods algorithm"))*.
