Two plots:
got optimisation proceedure. Plotted $\tau$ with respect to cost for:
Discovered that the number of steps doesn't really have much of an impact on the the integrated autocorrelation in HMC
Improved resolution
Instead of solely using the integrated autocorrelation, should use a cost function which takes into account the acceptance probability.
Aim Plot optimal parameters for HMC model
Method Vary step size and angle
It is important to stress that the $M^2$ measurements are made by taking a regular autocorrelation. Taking into account the exponential trajectories is not necessary for the integrated autocorrelations. Otherwise the form would be $cos^2 \omega s$ and $\tau_{\text{int}} \to \infty\ \forall s$
