Perhaps you should try some spelling variations:
"modified parameter optimizer algorithms" » "modified parameter optimized algorithms", "modified parameter optimized algorithm", "modified parameter optimization algorithms"
"modified adaptive solution algorithm" » "modified adaptive evolution algorithm", "modified adaptive convolution algorithms", "modified adaptive evolutionary algorithm", "modified passive 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 adaptive solution algorithm") OR ("modified parameter optimizer algorithms"))~.
• Removing quotes may allow a broader search: (( modified adaptive solution algorithm ) or ( modified parameter optimizer algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified adaptive solution algorithm") or ("modified parameter optimizer algorithms"))*.
