Perhaps you should try some spelling variations:
multiobjective optimisation » multiobjective optimization, objective optimization
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
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 multiobjective optimisation algorithm ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( machines using ibm algorithm ) OR ( modified multiobjective optimisation algorithm ))".
• Adding a wildcard symbol may retrieve word variants: (( machines using ibm algorithm ) OR ( modified multiobjective optimisation algorithm ))*.
