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