Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithms" » "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithms", "modified multiobjective estimation algorithm"
"code using source algorithm" » "code using our algorithm", "code using search algorithm", "code using force algorithm", "code using morse algorithm", "core using source algorithm"

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

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