Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithm" » "modified multiobjective optimization algorithms", "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithm"
"code learning mom algorithm" » "how learning mom algorithm", "code learning adam algorithm", "code learning mppt algorithm", "code learning _ algorithm", "code learning from algorithm", "code learning model algorithm", "code learnings from algorithm"

Try widening your search to All Fields.

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 mom algorithm") or ("modified multiobjective optimization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("code learning mom algorithm") OR ("modified multiobjective optimization algorithm")).
• Removing quotes may allow a broader search: (( code learning mom algorithm ) or ( modified multiobjective optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("code learning mom algorithm") or ("modified multiobjective optimization algorithm"))*.
