# Getting started

# To start your experience with SPOT you need to have SPOT installed. Please see the [Installation chapter](index.md) for further details.
# To use SPOT we have to import it and use one of the pre-build examples:
import spotpy  # Load the SPOT package into your working storage
from spotpy.examples.spot_setup_rosenbrock import (
    spot_setup,  # Import the two dimensional Rosenbrock example
)

# The example comes along with parameter boundaries, the Rosenbrock function, the optimal value of the function and RMSE as a likelihood.
# So we can directly start to analyse the Rosenbrock function with one of the algorithms. We start with a simple Monte Carlo sampling:
if __name__ == "__main__":
    # Give Monte Carlo algorithm the example setup and saves results in a RosenMC.csv file
    # spot_setup.slow = True
    sampler = spotpy.algorithms.mc(spot_setup(), dbname="RosenMC", dbformat="ram")

    # Now we can sample with the implemented Monte Carlo algortihm:
    sampler.sample(50000)  # Sample 50.000 parameter combinations
    results = sampler.getdata()
    # Now we want to have a look at the results. First we want to know, what the algorithm has done during the 10.000 iterations:
    spotpy.analyser.plot_parameterInteraction(results)
    posterior = spotpy.analyser.get_posterior(results, maximize=False)
    spotpy.analyser.plot_parameterInteraction(posterior)
    # Print the run with the lowest objective function
    print(spotpy.analyser.get_best_parameterset(results))
