Perhaps you should try some spelling variations:
"modified large estimation algorithms" » "modified large estimation algorithm", "modified large optimization algorithms", "modified large optimisation algorithm", "modified pose estimation algorithms", "modified large evaluation algorithms", "modified large variation algorithms", "modified male estimation 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 large estimation algorithms") OR ("modified objective solution algorithm"))~.
• Removing quotes may allow a broader search: (( modified large estimation algorithms ) or ( modified objective solution algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified large estimation algorithms") or ("modified objective solution algorithm"))*.
