+==== Quantifying overlaps between analysis search regions using ADLs ====
+Members: Sezen, Wolfgang (, Harrison)
+Find and visualize overlaps in a model-independent way, without generating events using simple descriptions done using an [[[[2019:groups:tools:adl|analysis description language]].  Directly sample the event selection.  Useful for analysis design phase, or quick comparisons within experiments (e.g. Run2 CMS SUSY pMSSM combination)
+  * Start from the analysis description, which lists objects and event selections.
+  * Construct a feature space from all mathematically orthogonal "basic" variables (e.g. MET, jet1.pt, jet2.pt, electron1.eta, ...).
+  * Randomly sample the feature space for each analysis based on cuts on the feature space components (jet1.pt > 100, MET > 299, etc.).
+  * Use the sampled points to compute values for "composite" variables such as HT(jets), dphi(jets), MT(lepton, MET), etc.
+  * Compare feature spaces between analyses, find and visualize overlaps and exclusions.
+  * As a very simple first step, we simply check if two analyses are disjoint in any of the basic variables.
