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"
"active learning method algorithm" » "active learning mom algorithm", "machine learning method algorithm", "active learning methods algorithm", "active graining methods algorithm", "active learning emotion algorithm"

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

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