LogisticMap

Benchmark of Logistic Map using integer caliculation and Flow.

Installation

It is available in Hex, so the package can be installed by adding logistic_map to your list of dependencies in mix.exs:

def deps do
  [
    {:logistic_map, "~> 0.1.0"}
  ]
end

Documentation can be generated with ExDoc and published on HexDocs. Once published, the docs can be found at https://hexdocs.pm/logistic_map.

Usage

To run benchmark,

$ mix run -e "LogisticMap.benchmarks"

benchmark calls calculation recursively from Flow.map.

def loopCalc(num, x, p, mu) do
  if num <= 0 do
    x
  else
    loopCalc(num - 1, calc(x, p, mu), p, mu)
  end
end

def mapCalc(list, num, p, mu, stages) do
  list
  |> Flow.from_enumerable(stages: stages)
  |> Flow.map(& loopCalc(num, &1, p, mu))
  |> Enum.to_list
end

benchmarks2 and benchmarks3 are variations of benchmark.

$ mix run -e "LogisticMap.benchmarks2"
$ mix run -e "LogisticMap.benchmarks3"

benchmarks2 inlines Flow.map as follows:

list
|> Flow.from_enumerable(stages: stages)
|> Flow.map(& calc(&1, p, mu))
|> Flow.map(& calc(&1, p, mu))
...
|> Flow.map(& calc(&1, p, mu))
|> Enum.to_list

benchmark3 inlines inside of Flow.map as folows:

list
|> Flow.from_enumerable(stages: stages)
|> Flow.map(& (&1
  |> calc(p, mu)
  |> calc(p, mu)
...
  |> calc(p, mu)
  ))
|> Enum.to_list
