Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithms" » "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithms", "modified multiobjective estimation algorithm"
"modified minimal solution algorithm" » "modified minimal evolution algorithm", "modified minimal convolution algorithms", "modified minimal evolutionary algorithm", "modified thermal solution algorithm", "modified optimal solution algorithm", "modified nodal solution algorithm"

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 minimal solution algorithm") OR ("modified multiobjective optimization algorithms"))~.
• Removing quotes may allow a broader search: (( modified minimal solution algorithm ) or ( modified multiobjective optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified minimal solution algorithm") or ("modified multiobjective optimization algorithms"))*.
