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 drug convolution algorithms" » "modified drug evolution algorithm", "modified drug solution algorithm", "modified drug solution algorithms", "modified df convolution algorithms", "modified orca 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 multiobjective optimisation algorithm") OR ("modified drug convolution algorithms"))~.
• Removing quotes may allow a broader search: (( modified multiobjective optimisation algorithm ) or ( modified drug convolution algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimisation algorithm") or ("modified drug convolution algorithms"))*.
