+The Sellar problem is an analytical multi-disciplinary design problem. The objective function f is to be minimized with respect to the variables z1, z2 and x1 while being subjected to g1, g2 and the disciplines y1 and y2.
+
+D1: y1 = z1^2 + x1 + z2 -0.2*y2
+D2: y2 = y1^0.5 + z1 + z2
+F1: f = x1^2 + z^2 + y1 + e^(-y2)
+G1: g1 = y1/3.16 - 1
+G2: g2 = 1 - y2/24
+
+More information on the Sellar problem can be found in literature, e.g. on
+https://arc.aiaa.org/doi/abs/10.2514/6.1996-714,

+The files in the subdirectories represent and illustrate Repository Connectivity Graphs (RCGs), Fundmental Problem Graphs (FPGs) and MDO Data/Process Graphs (MDG/MPG). These graphs were developed for a new software system called KADMOS which will be released in near future.
+
+In the RCG files two additional tools, D3 and G3, are present. They are consequently removed for the FPG files and demonstrate the KADMOS capabilities of tailoring a larger database down to a specific problem.
