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