Perhaps you should try some spelling variations:
"modified objective allocation algorithms" » "modified objective estimation algorithms", "modified objective approximation algorithms"
"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.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified objective allocation algorithms\") OR (\"modified model evolution algorithm\"))~".
• Removing quotes may allow a broader search: (( modified objective allocation algorithms ) OR ( modified model evolution algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective allocation algorithms") OR ("modified model evolution algorithm"))*.
