DEVS Solver

The actual DEVS solvers containing the main DEVS implementation

class pypdevs.solver.Solver(listeners={})

A unified DEVS solver, containing all necessary functions

__init__(listeners={})

Constructor

atomicInit(aDEVS, time)

AtomicDEVS function to initialise the model

Parameters

aDEVS – the model to initialise

atomicOutputGeneration(aDEVS, time)

AtomicDEVS function to generate output, invokes the outputFnc function of the model.

Parameters

• aDEVS – the AtomicDEVS model that generates the output

• time – the time at which the output must be generated

Returns

dict – the generated output

atomicOutputGenerationEventTracing(aDEVS, time)

Wrapper for the AtomicDEVS output function, which will save event counts

Parameters

• aDEVS – the AtomicDEVS model that generates the output

• time – the time at which the output must be generated

Returns

dict – the generated output

coupledInit()

CoupledDEVS function to initialise the model, calls all its _local_ children too.

coupledOutputGeneration(time)

CoupledDEVS function to generate the output, calls the atomicDEVS models where necessary. Output is routed too.

Parameters

time – the time at which output should be generated

Returns

the models that should be rescheduled

coupledOutputGenerationClassic(time)

CoupledDEVS function to generate the output, calls the atomicDEVS models where necessary. Output is routed too.

Parameters

time – the time at which output should be generated

Returns

the models that should be rescheduled

massAtomicTransitions(trans, clock)

AtomicDEVS function to perform all necessary transitions, does so on a collection of models for performance.

Parameters

• trans – iterable containing all models and their requested transition

• clock – the time at which the transition must happen

performDSDEVS(transitioning)

Perform Dynamic Structure detection of the model

Parameters

transitioning – iteratable to be checked for a dynamic structure transiton
