Perhaps you should try some spelling variations:
"modified multiobjective optimized algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective optimized algorithm", "modified multiobjective optimizer algorithms"
"mobile learning convolution algorithms" » "mobile learning evolution algorithm", "mobile learning solution algorithm", "machine learning 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: (("mobile learning convolution algorithms") OR ("modified multiobjective optimized algorithms"))~.
• Removing quotes may allow a broader search: (( mobile learning convolution algorithms ) or ( modified multiobjective optimized algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("mobile learning convolution algorithms") or ("modified multiobjective optimized algorithms"))*.
