Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithm" » "modified multiobjective optimization algorithms", "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithm"
"code control method algorithm" » "code control mom algorithm", "code control methods algorithm", "mode control method algorithm", "case control method algorithm", "order control method 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: "((\"code control method algorithm\") OR (\"modified multiobjective optimization algorithm\"))~".
• Removing quotes may allow a broader search: (( code control method algorithm ) OR ( modified multiobjective optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("code control method algorithm") OR ("modified multiobjective optimization algorithm"))*.
