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"
"modified water solution algorithm" » "modified water evolution algorithm", "modified water convolution algorithms", "modified water evolutionary algorithm", "modified male solution algorithm", "modified water absorption 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 water solution algorithm") or ("modified parameters optimization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified water solution algorithm") OR ("modified parameters optimization algorithm")).
• Removing quotes may allow a broader search: (( modified water solution algorithm ) or ( modified parameters optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified water solution algorithm") or ("modified parameters optimization algorithm"))*.
