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