Experiment Object

/experiments/EXPERIMENT_ID

An experiment represents an objective that SigOpt is optimizing, the relevant parameters, and the underlying data.

Fields

Key	Type	Value
`client`	`string`	The `id` of the Client who created this experiment.
`conditionals`	`array<Conditional>`	See conditionals.
`created`	`int`	The timestamp (in seconds since epoch) that this experiment was created.
`id`	`string`	A unique ID for this experiment.
`linear_constraints`	`array<Constraint>`	See constraints.
`metadata`	`Metadata`	Optional user-provided object. See Using Metadata for more information.
`metrics`	`array<Metric>`	An array of Metric objects to be optimized or stored for analysis. Use only a single entry for the standard single criterion optimization problem. This array can have no more than 2 entries marked for optimization and no more than 50 entries in total.
`name`	`string`	A user-specified name for this experiment.
`num_solutions`	`int`	The number of solutions you want for your experiment. The default number of solutions is 1. You can have up to 3 solutions. An observation budget is required if the number of solutions is greater than 1.
`observation_budget`	`int`	The number of Observations you plan to create for this experiment. We recommend this value be between 10x and 20x the number of parameters. This can be thought of as a lower bound on the number of observations you will create. Failing to reach this value may result in suboptimal performance for your experiment.
`parallel_bandwidth`	`int`	The number of simultaneously open Suggestions you plan to maintain during this experiment. The default value for this is 1, i.e., a sequential experiment. The maximum value for this is dependent on your plan. This field is optional, but setting it correctly may improve performance.
`parameters`	`array<Parameter>`	An array of Parameter objects.
`progress`	`Progress`	The current progress of this experiment.
`project`	`string`	The `id` of the project that this experiment belongs to.
`state`	`string`	The state of this experiment. Can be `active` (for experiments that are currently running), or `deleted` (for experiments that have been deleted).
`type`	`string`	A type for this experiment. Used for experimental and alpha features only.
`updated`	`int`	The timestamp (in seconds since epoch) that this experiment was last updated.
`user`	`string`	The `id` of the user who created this experiment.

Deprecated Fields

These fields should no longer be used because there are better alternatives.

Key	Type	Value
`metric`	`Metric`	Information about the Metric that this experiment is optimizing.
