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