First order hidden Markov model with Viterbi algorithm in Java
Introduction
A first order HMM (hidden Markov model) is a tuple \$(H, \Sigma, T, E, \mathbb{P})\,ドル where \$H = \{1, \ldots, \vert H \vert\}\$ is the set of hidden states, \$\Sigma\$ is the set of ...

Calculating the energy of the harmonic oscillator using a Monte Carlo method
The problem
The partition function for the quantum harmonic oscillator can be written in the path integral formulation as
$$Z\propto\int Dx(\tau)\exp\left(-\frac{S_E}{\hbar}\right)=\int Dx(\tau)\exp\...
