Perhaps you should try some spelling variations:
"certified network optimization algorithm" » "certified network optimization algorithms", "certified network optimisation algorithm", "certified network estimation algorithm", "verified network optimization algorithm"
"mapping forecasting method algorithm" » "mapping focusing method algorithm", "mapping forecasting mixed algorithm", "mapping forecasting mom algorithm"

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

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