A model generation apparatus trains a search module on training data pairs through machine learning to find a path fitting a recommended path indicated by true information in response to receiving an input of a training map as an input map. In the machine learning, the model generation apparatus performs, in a phase of forward propagation, an extraction operation and a selection operation, and replaces, in a phase of backpropagation, the extraction operation and the selection operation with differentiable alternative operations and differentiates the alternative operations to compute approximate gradients corresponding to differentiation calculations for the extraction operation and the selection operation.
