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