Perhaps you should try some spelling variations:
"modified parameter optimization algorithms" » "modified parameter optimisation algorithm", "modified parameter estimation algorithms", "modified parameter estimation algorithm", "modified parameters optimization algorithms"
"modified water convolution algorithms" » "modified water evolution algorithm", "modified water solution algorithm", "modified dilated convolution algorithms", "modified water solution algorithms", "modified male convolution algorithms"

Try widening your search to All Fields.

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