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