Perhaps you should try some spelling variations:
"modified exact evolutionary algorithm" » "modified exact evolution algorithm", "modified exact solution algorithm"
"modified objective optimisation algorithm" » "modified objective optimization algorithm", "modified multiobjective optimization algorithm", "modified objective optimization algorithms", "modified objective estimation algorithm", "modified objective estimation algorithms"

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 exact evolutionary algorithm\") OR (\"modified objective optimisation algorithm\"))~".
• Removing quotes may allow a broader search: (( modified exact evolutionary algorithm ) OR ( modified objective optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified exact evolutionary algorithm") OR ("modified objective optimisation algorithm"))*.
