Perhaps you should try some spelling variations:
simulation techniques » imputation techniques, segmentation techniques, inhalation technique
mitigation techniques » imputation techniques
a simulation » _ simulation
k mitigation » _ mitigation, _ litigation
based a » based _, based n, based 3d
based k » based _, based n, based 3d

• If you are trying to use Boolean operators, they must be ALL CAPS: (( learning-based a simulation techniques ) OR ( learning-based k mitigation techniques )).
• Adding a wildcard symbol may retrieve word variants: (( learning-based a simulation techniques ) or ( learning-based k mitigation techniques ))*.
