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