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 stochastic convolution algorithms" » "modified stochastic configuration algorithms", "modified stochastic evolution algorithm", "modified stochastic solution 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 parameter optimization algorithms") or ("modified stochastic convolution algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified parameter optimization algorithms") OR ("modified stochastic convolution algorithms"))*.
• Removing quotes may allow a broader search: (( modified parameter optimization algorithms ) or ( modified stochastic convolution algorithms ))*.
