Perhaps you should try some spelling variations:
"modified multiobjective optimisation algorithm" » "modified multiobjective optimization algorithm", "modified objective optimization algorithm", "modified multiobjective optimization algorithms", "modified multiobjective estimation algorithm", "modified multiobjective estimation algorithms"
"code using methods algorithm" » "code nursing methods algorithm", "code making methods algorithm", "code counting methods algorithm", "core using methods 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 using methods algorithm\") OR (\"modified multiobjective optimisation algorithm\"))~".
• Removing quotes may allow a broader search: (( code using methods algorithm ) OR ( modified multiobjective optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("code using methods algorithm") OR ("modified multiobjective optimisation algorithm"))*.
