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