Perhaps you should try some spelling variations:
"modified stochastic optimisation algorithm" » "modified stochastic optimization algorithm", "modified static optimization algorithm", "modified stochastic configuration algorithm", "modified stochastic optimization algorithms", "modified stochastic estimation algorithm", "modified stochastic estimation algorithms"
"modified learning convolution algorithms" » "modified learning evolution algorithm", "modified learning solution algorithm", "mobile learning convolution algorithms", "modified caging convolution algorithms"

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 optimisation algorithm") OR ("modified learning convolution algorithms"))~.
• Removing quotes may allow a broader search: (( modified stochastic optimisation algorithm ) or ( modified learning convolution algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified stochastic optimisation algorithm") or ("modified learning convolution algorithms"))*.
