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