Perhaps you should try some spelling variations:
"modified parameter estimation algorithm" » "modified parameter estimates algorithm", "modified parameter optimization algorithm"
"modified changing solution algorithm" » "modified changing evolution algorithm", "modified changing convolution algorithms", "modified changing evolutionary algorithm", "modified caging solution algorithm", "modified charging station 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 changing solution algorithm") or ("modified parameter estimation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified changing solution algorithm") OR ("modified parameter estimation algorithm"))*.
• Removing quotes may allow a broader search: (( modified changing solution algorithm ) or ( modified parameter estimation algorithm ))*.
