This is a collection of benchmark I collected over the years. In this blog post here I describe what I did and how new benchmarks can be added. For more results of a benchmark, please have a look in the respective folder within benchmarks.
- The DATE of the last time, the benchmark run.
- A short description TEST of the benchmark.
- In the COMMENTS I tried to give a hint of what the setups looked like.
- The BEST option out of all tested alternatives compared by their mean time.
- The TIME_FACTOR presents the mean time that can be saved with the best option compared with the mean of the alternatives over all grid setups. Note: The time factor can be negative if the best option is not the best in the cases where it takes more time. For these cases, have a look at the details and dependencies of the grid parameters.
- BEST_RUNS is the number of cases were BEST solution was actually the best one in relation of all different varying setups that were used (e.g. sample size).
- DURATION is the time the whole benchmark with all setups took.
