Bias Sampling towards Goal #12

Open SZanlongo opened 6 years ago

SZanlongo commented 6 years ago

Allow for sampling to be biased towards the goal as time moves on. Example: sample from a normal distribution biased towards the goal, where the bias increases over time as

bias = t / (t + r)

where r is a constant that tunes the steepness of the curve.
