# graphOptimizerState

A graph optimizer state record carrying key, optimizerKind, learningRate, momentum, weightDecay, and related state.

Package: compute.graph | Status: source-declared

Tags: compute, compute.graph, cpu, graph, method, source-example, thing, yeho

Describe compute work as an explicit graph with package-owned validation and scheduling metadata.

```yh
external thing graphOptimizerState
```

- text key: Stores key as text.
- text optimizerKind: Stores optimizer kind as text.
- text learningRate: Stores learning rate as text.
- text momentum: Stores momentum as text.
- text weightDecay: Stores weight decay as text.
- int step: Stores step as int.
- text note: Stores note as text.
- graphOptimizerState(text key, text optimizerKind, text learningRate, text momentum, text weightDecay, int step, text note): Graph optimizer state.
- Describe() returns text: Describe.

## Use graphOptimizerState

A complete small caller. Values are illustrative; check the returned result and package requirements before connecting live resources.

Verification: type checked

```yh
using compute.graph

// Describe compute work as an explicit graph with package-owned validation and scheduling metadata.
graphOptimizerState sample = graphOptimizerState("key", "optimizer Kind", "learning Rate", "momentum", "weight Decay", 1, "note")
Console.Log(Text.From(sample.key))

```

Save this beside start.yh as project.mech:

Extract the example archive beside the yeho and dolphin checkouts. This example requires those source dependencies and a current developer compiler.

```sh
./yeho/build/dolphin-metal/yehoc ./api-examples/compute.graph--graphOptimizerState/usage --backend cpu-oracle -o /tmp/yeho-example
/tmp/yeho-example
```


## graphOptimizerState.Describe

A complete caller for this public method. Sample inputs are illustrative; native resources require their owning lifecycle.

Verification: type checked

```yh
using compute.graph

// Describe.
graphOptimizerState instance = graphOptimizerState("key", "optimizer Kind", "learning Rate", "momentum", "weight Decay", 1, "note")
text result = instance.Describe()
Console.Log(Text.From(result))

```

Package presence and a declaration do not establish support on every host. Host services need their platform and lifecycle setup.
