Perhaps you should try some spelling variations:
"modified parameters optimization algorithm" » "modified parameter optimization algorithm", "modified parameter estimation algorithm", "modified parameters optimization algorithms", "modified parameters optimisation algorithm", "modified parameters estimation algorithm"
"machine learning solution algorithm" » "machine learning evolution algorithm", "machine learning convolution algorithms", "machine learning evolutionary algorithm", "machine learning convolution algorithm", "machine learning emotion algorithm"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("machine learning solution algorithm") or ("modified parameters optimization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("machine learning solution algorithm") OR ("modified parameters optimization algorithm")).
• Removing quotes may allow a broader search: (( machine learning solution algorithm ) or ( modified parameters optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("machine learning solution algorithm") or ("modified parameters optimization algorithm"))*.
