Perhaps you should try some spelling variations:
"modified based optimisation algorithm" » "modified based optimization algorithms", "modified based estimation algorithm", "modified based estimation algorithms", "modified game optimization algorithm", "modified male optimisation algorithm"
"modified objective evolutionary algorithm" » "modified objective evolution algorithm", "modified objective solution 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 based optimisation algorithm\") OR (\"modified objective evolutionary algorithm\"))~".
• Removing quotes may allow a broader search: (( modified based optimisation algorithm ) OR ( modified objective evolutionary algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified based optimisation algorithm") OR ("modified objective evolutionary algorithm"))*.
