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"
"defined network optimized algorithm" » "defined network optimized algorithms", "defined network optimizer algorithms", "defined 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 optimization algorithm") or ("defined network optimized algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified parameter optimization algorithm") OR ("defined network optimized algorithm"))*.
• Removing quotes may allow a broader search: (( modified parameter optimization algorithm ) or ( defined network optimized algorithm ))*.
