Perhaps you should try some spelling variations:
"modified objective optimisation algorithm" » "modified objective optimization algorithm", "modified multiobjective optimization algorithm", "modified objective optimization algorithms", "modified objective estimation algorithm", "modified objective estimation algorithms"
"mobile learning solution algorithm" » "mobile learning evolution algorithm", "mobile learning convolution algorithms", "mobile learning evolutionary algorithm", "mobile learning convolution algorithm", "mobile learning emotion algorithm", "machine learning solution 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 objective optimisation algorithm\") OR (\"mobile learning solution algorithm\"))~".
• Removing quotes may allow a broader search: (( modified objective optimisation algorithm ) OR ( mobile learning solution algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective optimisation algorithm") OR ("mobile learning solution algorithm"))*.
