Simulator constructor.

• field: An object of type EnergyField encapsulating the energy function (cost function) and search space.

---

Optional parameters:

• gammaStart: Expectation value of the solution acceptance at the
• gammaEnd: Expectation value of the solution acceptance at the
• outerIterations: Number of iterations when cooling.
• innerIterationsStart: Number of iterations at constant temperature at the start of the annealing process.
• innerIterationsEnd: Number of iterations at constant temperature at the end of the annealing process.
• sampleSize: Size of sample used to estimate the start temperature and the final temperature of the annealing process.
