Perhaps you should try some spelling variations:
"modified notion estimation algorithms" » "modified notion estimation algorithm", "modified notion optimization algorithms", "modified notion optimisation algorithm", "modified motion estimation algorithms"
"modified global evolution algorithm" » "modified global solution algorithm", "modified global evolutionary algorithm", "modified global convolution algorithms", "modified global solutions algorithm", "modified global production algorithm", "modified global edition 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 global evolution algorithm") OR ("modified notion estimation algorithms"))~.
• Removing quotes may allow a broader search: (( modified global evolution algorithm ) or ( modified notion estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified global evolution algorithm") or ("modified notion estimation algorithms"))*.
