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