gosim

A simple discrete event simulator in go

Build and Install

go get github.com/fengttt/gosim/...

The examples use pixel for display. Please follow the instruction to install requirements. For example, on ubuntu 18LTS, you need to

sudo apt isntall libgl1-meda-dev xorg-dev libglfw3 libglfw3-dev

If you are using windows, you need to follow build pixel on windows.

Examples

conway is a simulator for Conway's Game of Life. It includes several interesting inintial configurations.

go run examples/conway/conway.go diehard

spread is a very simple model for infectious disease.

go run examples/spread/spread.go -n 10 -r 0.08

Types ¶

type Agg ¶

type Agg interface {
	Update(ival int64, fval float64)
	Get() (int64, float64)
	Gather(a Agg)
	Reset()
}

type Lp ¶

type Lp interface {
	Run(s *Sim, r *Runner, msgs []interface{}) int64
}

Logic Process, which can run at certain tic. Run should return

positive int64, means this lp should be run again, at tic + ret
0, means put this lp to sleep.
-1, means this lp should die,

type Lpid ¶

type Lpid struct {
	RunnerId   int
	Id         int
	CreateTick int64
}

LP id

type Runner ¶

type Runner struct {
	// contains filtered or unexported fields
}

Runner runs LPs.

func (*Runner) AddLp ¶

func (r *Runner) AddLp(s *Sim, lp Lp) Lpid

func (*Runner) Rand ¶

func (r *Runner) Rand() *rand.Rand

func (*Runner) RemoveLp ¶

func (r *Runner) RemoveLp(lpid Lpid)

func (*Runner) UpdateAgg ¶

func (r *Runner) UpdateAgg(aggId int, ival int64, fval float64)

type Sim ¶

type Sim struct {
	// contains filtered or unexported fields
}
