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"
"modified early convolution algorithms" » "modified early evolution algorithm", "modified early solution algorithm", "modified early evolution algorithms", "modified learning convolution algorithms", "modified male convolution algorithms", "modified near convolution algorithms"

You may be able to get more results by adjusting your search query.

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