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 learning method algorithm" » "mobile learning method algorithm", "modified caging method algorithm", "modified learning mom algorithm", "modified learning methods algorithm", "modified graining methods algorithm", "modified learning emotion algorithm"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified multiobjective optimisation algorithm\") OR (\"modified learning method algorithm\"))~".
• Removing quotes may allow a broader search: (( modified multiobjective optimisation algorithm ) OR ( modified learning method algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimisation algorithm") OR ("modified learning method algorithm"))*.
