Accessors

name

Get Signature

get name(): undefined | string

The name assigned to this model element.

Remarks

The name is optional and primarily useful for debugging purposes. When set, it helps identify the element in solver logs, error messages, and when inspecting solutions.

Names can be assigned to any model element including variables, expressions, and constraints.

Example

import * as CP from "optalcp";

const model = new CP.Model();

// Name a variable at creation
const task = model.intervalVar({ length: 10, name: "assembly" });

// Or set name later
const x = model.intVar({ min: 0, max: 100 });
x.name = "quantity";

console.log(task.name);  // "assembly"
console.log(x.name);     // "quantity"

Returns
