CoolingScheduleSpec

@Serializable

sealed class CoolingScheduleSpec(source)

Cooling-schedule selection for a simulated-annealing solver.

Mirrors the three ksl.simopt.solvers.algorithms.CoolingScheduleIfc implementations: linear, exponential, and logarithmic cooling.

The initialTemperature field on each variant is the temperature at iteration 0; for an Exponential schedule the temperature at iteration i is initialTemperature * coolingRate^i.

Types

Exponential

@Serializable

@SerialName(value = "exponential")

data class Exponential(val initialTemperature: Double, val coolingRate: Double = 0.95) : CoolingScheduleSpec

Geometric cooling: temperature at iteration i is initialTemperature * coolingRate^i.

Linear

@Serializable

@SerialName(value = "linear")

data class Linear(val initialTemperature: Double, val stoppingTemperature: Double, val maxIterations: Int) : CoolingScheduleSpec

Linear cooling between initialTemperature and stoppingTemperature over maxIterations iterations.

Logarithmic

@Serializable

@SerialName(value = "logarithmic")

data class Logarithmic(val initialTemperature: Double) : CoolingScheduleSpec

Logarithmic cooling; very slow but with theoretical convergence guarantees.
