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