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 make solution algorithm" » "modified make evolution algorithm", "modified make convolution algorithms", "modified make evolutionary algorithm", "modified male solution algorithm", "modified water solution algorithm", "modified nacl solution algorithm"

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified network optimization algorithm") or ("modified make solution algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified network optimization algorithm") OR ("modified make solution algorithm")).
• Removing quotes may allow a broader search: (( modified network optimization algorithm ) or ( modified make solution algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified network optimization algorithm") or ("modified make solution algorithm"))*.
