This the analyzer for the empirical performance of Iterative Optimization Heuristics (IOHs). It provides two perspectives to look at the empirical performance:

• Fixed-Target running time: focuses on the distribution of running time (a.k.a. the number of function evaluations) at various given target values (thus called “fixed-target”), functions and dimensions.
• Fixed-Budget results: focuses on the distribution of the best function value at various given budget values (thus called “fixed-budget”), functions and dimensions.

To get started, you could

• upload your own dataset using the Upload Data box on the bottom left. The supported format is specified in the <a href=“#shiny-tab-dataformat”, data-toggle=“tab”>data format tab.
• or choose one of the pre-loaded datasets in the Load Data from Repository box on the bottom right and directly explore the analyzer.

In details, the following functionalities are provided:

	Data Summary	Expected Values	Probability Density/Mass Function	Empirical Cumulative Distribution (ECDF)
