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