Pulp stones appear to have no clinical significance. The explanation is that the Python variable x is not the decision variable itself, it is a PuLP object of type LpVariable: In[5]: type(x) Out[5]: pulp.pulp.LpVariable Therefore, just using print(x) does not give you the value of the decision variable, it gives you the variable name that you supplied in the name argument when you declared your LpVariable .
