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 thermal estimation algorithms" » "modified thermal estimation algorithm", "modified thermal optimization algorithms", "modified thermal approximation algorithms", "modified thermal activation algorithms", "modified thermal oxidation 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 thermal estimation algorithms"))~.
• Removing quotes may allow a broader search: (( modified multiobjective optimisation algorithm ) or ( modified thermal estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimisation algorithm") or ("modified thermal estimation algorithms"))*.
