Perhaps you should try some spelling variations:
"modified parameters estimation algorithm" » "modified parameter estimation algorithm", "modified parameter estimates algorithm", "modified parameter optimization algorithm"
"modified optimal solution algorithm" » "modified optimal evolution algorithm", "modified optimal convolution algorithms", "modified optimal evolutionary algorithm", "modified thermal solution algorithm"

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified optimal solution algorithm") OR ("modified parameters estimation algorithm"))~.
• Removing quotes may allow a broader search: (( modified optimal solution algorithm ) or ( modified parameters estimation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified optimal solution algorithm") or ("modified parameters estimation algorithm"))*.
