Perhaps you should try some spelling variations:
"modified response optimizer algorithms" » "modified response optimized algorithms", "modified response optimized algorithm", "modified response optimization algorithms"
"modified objective solution algorithm" » "modified objective evolutionary algorithm", "modified objective allocation algorithm", "modified objective evolution algorithm", "modified objective convolution algorithms"

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 objective solution algorithm") OR ("modified response optimizer algorithms"))~.
• Removing quotes may allow a broader search: (( modified objective solution algorithm ) or ( modified response optimizer algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective solution algorithm") or ("modified response optimizer algorithms"))*.
