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 objective estimation algorithmss" » "modified objective estimation algorithms", "modified objective estimation algorithm", "modified objective optimization algorithms", "modified objective optimization algorithmss", "modified objective allocation algorithmss"

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 objective estimation algorithmss"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified network optimization algorithm") OR ("modified objective estimation algorithmss")).
• Removing quotes may allow a broader search: (( modified network optimization algorithm ) or ( modified objective estimation algorithmss )).
• Adding a wildcard symbol may retrieve word variants: (("modified network optimization algorithm") or ("modified objective estimation algorithmss"))*.
