Perhaps you should try some spelling variations:
"modified parameters optimization algorithmsss" » "modified parameters optimization algorithms", "modified parameters estimation algorithms", "modified parameter optimization algorithmsss", "modified parameter estimation algorithmsss"
"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"

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

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