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 df evolution algorithms" » "modified df evolution algorithm", "modified df convolution algorithms", "modified df solution algorithm", "modified _ evolution algorithms", "modified co evolution algorithms", "modified adam evolution algorithms", "modified bi1 evolution 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 df evolution algorithms"))~.
• Removing quotes may allow a broader search: (( modified multiobjective optimisation algorithm ) or ( modified df evolution algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimisation algorithm") or ("modified df evolution algorithms"))*.
