Perhaps you should try some spelling variations:
"modified parameter optimization algorithm" » "modified parameter optimization algorithms", "modified parameter optimisation algorithm", "modified parameter estimation algorithm", "modified parameters optimization algorithm"
"modified network optimizer algorithmss" » "modified network optimizer algorithms", "modified network optimized algorithms", "modified network optimized algorithm", "modified network optimization algorithmss", "certified network optimizer algorithmss", "defined network optimizer algorithmss", "modified near optimizer algorithmss"

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 optimization algorithm") OR ("modified network optimizer algorithmss"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified parameter optimization algorithm\") OR (\"modified network optimizer algorithmss\"))".
• Removing quotes may allow a broader search: (( modified parameter optimization algorithm ) OR ( modified network optimizer algorithmss )).
• Adding a wildcard symbol may retrieve word variants: (("modified parameter optimization algorithm") OR ("modified network optimizer algorithmss"))*.
