Perhaps you should try some spelling variations:
"modified objective optimisation algorithm" » "modified objective optimization algorithm", "modified multiobjective optimization algorithm", "modified objective optimization algorithms", "modified objective estimation algorithm", "modified objective estimation algorithms"
"code learning method algorithm" » "code learning mom algorithm", "code learning methods algorithm", "code graining methods algorithm", "code learning emotion algorithm", "how learning method 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 learning method algorithm") or ("modified objective optimisation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("code learning method algorithm") OR ("modified objective optimisation algorithm")).
• Removing quotes may allow a broader search: (( code learning method algorithm ) or ( modified objective optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("code learning method algorithm") or ("modified objective optimisation algorithm"))*.
