Struct TrialRecord 

pub struct TrialRecord {
    pub number: u64,
    pub sampler_seed: u64,
    pub params: Vec<f64>,
    pub value: f64,
    pub cost: Option<f64>,
    pub best_so_far: Option<f64>,
    pub outcome: TrialOutcome,
    pub origin: TrialOrigin,
    pub policy: Option<[f64; 5]>,
}

One transaction as the demo shows it: a trial run, or a paused trial’s resumed remainder.

Fields

number: u64

The per-study trial number (from 0).

sampler_seed: u64

The per-trial sampler seed derived from the study seed and number.

params: Vec<f64>

Parameter values, in crate::problem::Problem::bounds order.

value: f64

The objective value: the told value of a completed trial, else its last report.

cost: Option<f64>

CARBS’s declared cost, the second objective.

best_so_far: Option<f64>

The lowest completed value up to and including this transaction.

outcome: TrialOutcome

How the transaction ended.

origin: TrialOrigin

Where its trial came from.

policy: Option<[f64; 5]>

For cart-pole, the trained policy’s weights when the transaction ended.
