Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithm" » "modified multiobjective optimization algorithms", "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithm"
"modified saline convolution algorithms" » "modified saline evolution algorithm", "modified saline solution algorithm", "modified saline solution algorithms", "modified learning convolution algorithms", "modified caging convolution algorithms", "modified male convolution algorithms", "modified passive 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 optimization algorithm") OR ("modified saline convolution algorithms"))~.
• Removing quotes may allow a broader search: (( modified multiobjective optimization algorithm ) or ( modified saline convolution algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimization algorithm") or ("modified saline convolution algorithms"))*.
