Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
objective optimization » multiobjective optimization
machines using » machinery using
ibm algorithm » mom algorithm, adam algorithm, _ algorithm
using ibm » using rbf

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

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