Object-Oriented Probabilistic Relational Model

import pyAgrum.lib.notebook as gnb

O3PRM is inspired by relational language, directly based on the BN and improved by object oriented paradigms, where the focus is set on classes of objects and by defining relations among these objects (see http://o3prm.gitlab.io/ for more details)

O3PRM syntax

with open('./Asia.o3prm','r') as prm:
  for line in prm.readlines():
    print(line,end="")

             0.01, 0.05 ] // True
    };
