Perhaps you should try some spelling variations:
"modified parameters optimization algorithms" » "modified parameters optimisation algorithm", "modified parameters estimation algorithms", "modified parameters estimation algorithm", "modified parameter optimization algorithms", "modified parameter estimation algorithms"
"modified invasive convolution algorithms" » "modified invasive evolution algorithm", "modified invasive solution algorithm", "modified invasive ventilation algorithms", "modified passive convolution algorithms"

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

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