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 multiobjective estimation algorithms"
"modified thermal evolution algorithm" » "modified thermal solution algorithm", "modified thermal evolutionary algorithm", "modified thermal convolution algorithms", "modified thermal evaporation algorithm", "modified thermal regulation algorithm"

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified thermal evolution algorithm") or ("modified multiobjective optimisation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified thermal evolution algorithm") OR ("modified multiobjective optimisation algorithm")).
• Removing quotes may allow a broader search: (( modified thermal evolution algorithm ) or ( modified multiobjective optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified thermal evolution algorithm") or ("modified multiobjective optimisation algorithm"))*.
