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