EVEREST vs. ERT data models
6060
===========================
6161
EVEREST uses ERT for running an experiment. Whenver an EVEREST `experiment` is ran, `everserver` creates an `EverestRunModel` based on the
62-
`ErtConfig` (obtained from `EverestConfig`). The `ErtConfig` requires an `EnsembleConfig`. Here we map EVEREST `objectives` (i.e., objective functions)
63-
and `constraints` to `responses` in ERT using `GenDataConfig` (stored in `EnsembleConfig.response_config`).
64-
In `everest_to_ert_config` we map all the EVEREST `controls` to ERT `parameters` using `ExtParamConfig` (stored in `EnsembleConfig.parameter_configs`).
65-
Then in `EverestRunModel._forward_model_evaluator` (used as evaluator by the external optimization library `ropt`) we create a local storage for the `batch` (i.e., `ensemble`),
66-
link to the current `experiment`, and setup up `simulations` for a set of `controls`.

All the forward models in the `batch` are then evaluated in ERT using `EverestRunModel._evaluate_and_postprocess` (and in turn `BaseRunModel.run_workflows`)

which uses the `EnsembleEvaluator` for execution. After ERT writes to `simulation_results` and stores results in the `LocalEnsemble` (i.e., storage)

to `simulation_results` and stores results in the `LocalEnsemble` (i.e., storage)
7072
these results are then gathered in the forward model evaluator (called by `ropt`) and feedforward into the optimizer using
71-
`EverestRunModel._gather_simulation_results` (i.e., reading the `.parquet` files generated by ERT). Every set of forward model executions for a single
72-
set of inputs (`controls`) and outputs (`objectives` / `constraints`) constitutes an ERT `realization` in the ERT queue system; denoted in EVEREST as `simulation`.

Since EVEREST optimizes a set of `controls` and assumes static (i.e., unchanging) `realizations`, there is a distinction between `unperturbed controls`
75-
(i.e., current `objective function` value) and `perturbed controls` (i.e., required to calculate the `gradient`).

Furthermore, when performing robust optimization (i.e., multiple static `realizations`) a `batch` contains a
7780
certain number of `realizations` (denoted by `<GEO_ID>`) and each `realization` contains a number of `simulations`
7881
(i.e., forward model runs). These `simulations` are forward model runs for either `unperturbed controls` and/or
