Perhaps you should try some spelling variations:
"modified parameter optimisation algorithm" » "modified parameter optimization algorithm", "modified parameter estimation algorithm", "modified parameter optimization algorithms", "modified parameter estimation algorithms"
"certified network optimization algorithm" » "certified network optimization algorithms", "certified network estimation algorithm", "certified network estimation algorithms", "verified network optimization 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 parameter optimisation algorithm") OR ("certified network optimization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified parameter optimisation algorithm\") OR (\"certified network optimization algorithm\"))".
• Removing quotes may allow a broader search: (( modified parameter optimisation algorithm ) OR ( certified network optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified parameter optimisation algorithm") OR ("certified network optimization algorithm"))*.
