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 model solutions algorithm" » "modified model solution algorithm", "modified model evolution algorithm", "modified model evolutionary algorithm", "modified nodal solution algorithm", "modified global solutions algorithm", "modified male solutions 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 model solutions algorithm\") OR (\"modified multiobjective optimisation algorithm\"))~".
• Removing quotes may allow a broader search: (( modified model solutions algorithm ) OR ( modified multiobjective optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified model solutions algorithm") OR ("modified multiobjective optimisation algorithm"))*.
