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