Perhaps you should try some spelling variations:
"modified multiobjective source algorithm" » "modified multiobjective lot algorithm", "modified multiobjective our algorithm", "modified multiobjective search algorithm"
"modified objective allocation algorithms" » "modified objective estimation algorithms", "modified objective approximation algorithms"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified multiobjective source algorithm") OR ("modified objective allocation algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified multiobjective source algorithm\") OR (\"modified objective allocation algorithms\"))*".
• Removing quotes may allow a broader search: (( modified multiobjective source algorithm ) OR ( modified objective allocation algorithms ))*.
