Perhaps you should try some spelling variations:
"modified objective optimization algorithm" » "modified multiobjective optimization algorithm", "modified objective optimization algorithms", "modified objective optimisation algorithm", "modified objective estimation algorithm"
"modified model evolution algorithm" » "modified model solution algorithm", "modified model evolutionary algorithm", "modified model convolution algorithms", "modified model solutions algorithm", "modified global evolution algorithm", "modified male evolution algorithm"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified objective optimization algorithm") OR ("modified model evolution algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified objective optimization algorithm\") OR (\"modified model evolution algorithm\"))".
• Removing quotes may allow a broader search: (( modified objective optimization algorithm ) OR ( modified model evolution algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified objective optimization algorithm") OR ("modified model evolution algorithm"))*.
