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 graining methods algorithm" » "modified caging methods algorithm", "modified learning methods algorithm", "modified learning method algorithm", "modified making methods algorithm"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified graining methods algorithm") OR ("modified network optimization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified graining methods algorithm\") OR (\"modified network optimization algorithm\"))".
• Removing quotes may allow a broader search: (( modified graining methods algorithm ) OR ( modified network optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified graining methods algorithm") OR ("modified network optimization algorithm"))*.
