Perhaps you should try some spelling variations:
"modified stochastic convolution algorithms" » "modified stochastic configuration algorithms", "modified stochastic evolution algorithm", "modified stochastic solution algorithm"
"defined network optimization algorithm" » "defined network optimization algorithms", "defined network optimisation algorithm", "defined network estimation 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 convolution algorithms") OR ("defined network optimization algorithm"))~.
• Removing quotes may allow a broader search: (( modified stochastic convolution algorithms ) or ( defined network optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified stochastic convolution algorithms") or ("defined network optimization algorithm"))*.
