Perhaps you should try some spelling variations:
mitigation techniques » imputation techniques
inhalation technique » floatation technique, implantation technique, imputation techniques
n inhalation » _ inhalation, _ inflation, k inflation
based code » based anode
based n » based _, based k, based no2

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: "(( learning-based code mitigation techniques ) OR ( learning-based n inhalation technique ))~".
• Adding a wildcard symbol may retrieve word variants: (( learning-based code mitigation techniques ) OR ( learning-based n inhalation technique ))*.
