The `GADGET`

package computes near-optimal Bayesian experimental designs using Gaussian process optimization. At its core is the ability to calculate static designs that maximize a design criterion that may be either deterministic or stochastic. In particular, stochastic design criteria could be a Monte Carlo estimator of an expected utility based on MCMC posterior draws. `GADGET`

utilizes the algorithm proposed by Weaver et al. (2016) <doi:10.1214/15-BA945> and performs Gaussian process validation using the statistics introduced by Bastos and O’Hagan (2009) <doi:10.1198/TECH.2009.08019>. The `pbapply`

package is integrated to parallelize the evaluation of the user's design criterion. Additionally, `GADGET`

has wrapped the optimization into a sequential routine to perform sequential computer experiments that automatically call simulator code that is available in R.
