Proposes a move in state space.
An operator which selects samples from a series of other operators, with respect to their ability to explore one or more real/int parameters Training for each operator occurs following a burn-in period After a learning period, AdaptableOperatorSampler should pick the operator which is giving the best results n a particular data set

| type: beast.base.core.Function*** |
| list of parameters to compare before and after the proposal. If the tree heights are a parameter then include the tree under 'tree' |
| Optional input |
| type: beast.base.evolution.tree.Tree*** |
| tree(s) containing node heights to compare before and after the proposal (optional) |
| Optional input |
| type: beast.base.inference.Operator*** |
| list of operators to select from |
| Optional input |
| type: java.lang.Integer |
| number of operator calls until the learning process begins (default: 1000) |
| Optional input. Default: 1000 |
| type: java.lang.Integer |
| number of operator calls after learning begins (ie. at burnin) but before this operator starts to use what it has learned (default: 100 x number of operators) |
| Optional input |
| type: java.lang.Double |
| the probability that operators are sampled uniformly at random instead of using the trained parameters (default 0.1) |
| Optional input. Default: 0.1 |
| type: beast.base.evolution.tree.TreeMetric |
| A function for computing the distance between trees. If left empty, then tree distances will not be compared |
| Optional input |
| type: java.lang.Double |
| The maximum amount of time (ms) to count towards the runtime of an operator. This should ensure that indefinite thread interruptions,eg. on a cluster, do not unfairly penalise an operator for being slow |
| Optional input. Default: 1000000.0 |
| type: java.lang.Boolean |
| Whether to set the weight of this operator as the dimension of its parameter |
| Optional input. Default: false |
| type: java.lang.Double |
| weight with which this operator is selected |
| Required input |
