coupling matrix » coupling metrics (Expand search), coupling machine (Expand search)
coder coupling » mode coupling (Expand search), model coupling (Expand search), core coupling (Expand search)

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( coder python codigo python programming ) OR ( coder coupling matrix java programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( coder python codigo python programming ) OR ( coder coupling matrix java programming ))*.
