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 pulse estimation algorithms" » "modified pulse estimation algorithm", "modified pulse optimization algorithms", "modified pulse approximation algorithms", "modified pulses estimation algorithms", "modified pose estimation algorithms", "modified sphere estimation algorithms", "modified male estimation algorithms", "modified passive estimation 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 pulse estimation algorithms") OR ("modified multiobjective optimisation algorithm"))~.
• Removing quotes may allow a broader search: (( modified pulse estimation algorithms ) or ( modified multiobjective optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified pulse estimation algorithms") or ("modified multiobjective optimisation algorithm"))*.
