Often simplifying assumptions are knit into the hypothesis and the afterwards built model

False

3 Why should one have several runs of a generative probabilistic model?

in the first run the caches need to warm up
to get statistic stability
because random experiments can produce strong outliers in just one run
there is no cost of making sure the computer did correct calculations by running the experiment twice or more
because every scientific experiment should be repeated more than once to avoid mistakes
