    "abstract": "A quantum Monte Carlo method is introduced to optimize excited state trial\nwavefunctions. The method is applied in a correlation function Monte Carlo\ncalculation to compute ground and excited state energies of bosonic van der\nWaals clusters of upto seven particles. The calculations are performed using\ntrial wavefunctions with general three-body correlations.",
