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 caging evolution algorithm" » "modified caging solution algorithm", "modified caging evolutionary algorithm", "modified caging convolution algorithms", "modified aging evolution algorithm", "modified changing evolution algorithm", "modified charging evolution 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 multiobjective optimisation algorithm") or ("modified caging evolution algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified multiobjective optimisation algorithm") OR ("modified caging evolution algorithm")).
• Removing quotes may allow a broader search: (( modified multiobjective optimisation algorithm ) or ( modified caging evolution algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimisation algorithm") or ("modified caging evolution algorithm"))*.
