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"

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"))*.
