Perhaps you should try some spelling variations:
"modified objective allocation algorithm" » "modified objective estimation algorithm", "modified objective evolution algorithm", "modified objective predation algorithm"
"modified make solution algorithm" » "modified make evolution algorithm", "modified make convolution algorithms", "modified make evolutionary algorithm", "modified male solution algorithm", "modified water solution algorithm", "modified nacl 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 make solution algorithm") OR ("modified objective allocation algorithm"))~.
• Removing quotes may allow a broader search: (( modified make solution algorithm ) or ( modified objective allocation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified make solution algorithm") or ("modified objective allocation algorithm"))*.
