Perhaps you should try some spelling variations:
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
caging optimisation » staffing optimization
solution algorithm » evolution algorithm, convolution algorithms, evolutionary algorithm
modified learning » mobile learning
learning solution » learning convolution, learning emotion

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

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