Perhaps you should try some spelling variations:
"modified multiobjective estimation algorithm" » "modified multiobjective optimization algorithm"
"modified notion optimisation algorithms" » "modified notion optimisation algorithm", "modified notion optimization algorithms", "modified notion estimation algorithms", "modified network optimization 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 estimation algorithm") OR ("modified notion optimisation algorithms"))~.
• Removing quotes may allow a broader search: (( modified multiobjective estimation algorithm ) or ( modified notion optimisation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective estimation algorithm") or ("modified notion optimisation algorithms"))*.
