Perhaps you should try some spelling variations:
"modified network optimization algorithms" » "modified network optimisation algorithm", "modified network estimation algorithms", "modified network estimation algorithm", "certified network optimization algorithms", "defined network optimization algorithms", "modified near optimization algorithms"
"code control method algorithm" » "code control mom algorithm", "code control methods algorithm", "mode control method algorithm", "case control method algorithm", "order control method algorithm"

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

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