Perhaps you should try some spelling variations:
"modified network optimisation algorithm" » "modified network optimization algorithms", "modified network estimation algorithm", "modified network estimation algorithms", "modified network optimization algorithm", "certified network optimisation algorithm", "defined network optimisation algorithm", "modified near optimisation algorithm"
"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 optimisation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("code control method algorithm") OR ("modified network optimisation algorithm")).
• Removing quotes may allow a broader search: (( code control method algorithm ) or ( modified network optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("code control method algorithm") or ("modified network optimisation algorithm"))*.
