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