Perhaps you should try some spelling variations:
"modified optimal evolutionary algorithm" » "modified optimal evolution algorithm", "modified optimal solution algorithm", "modified thermal evolutionary algorithm"
"modified objective solution algorithm" » "modified objective evolutionary algorithm", "modified objective allocation algorithm", "modified objective evolution algorithm", "modified objective convolution algorithms", "modified objective estimation 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 optimal evolutionary algorithm") OR ("modified objective solution algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified optimal evolutionary algorithm\") OR (\"modified objective solution algorithm\"))".
• Removing quotes may allow a broader search: (( modified optimal evolutionary algorithm ) OR ( modified objective solution algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified optimal evolutionary algorithm") OR ("modified objective solution algorithm"))*.
