+# Nonlinear Programming Solver (nlpsolver)
+
+This extension integrates into LibreOffice Calc and offers new Solver engines to use for optimizing
+nonlinear programming models.
+
+As there is no known upstream source for `nlpsolver/ThirdParty/EvolutionarySolver`,
+the code is considered internal and can be modified like any other internal code.

Due to the random nature of the algorithms, it is <emph>highly recommended</emph> to do so and give upper (and in case "Assume Non-Negative Variables" is turned off also lower) bounds for all variables. They don't have to be near the actual solution (which is probably unknown) but should give a rough indication of the expected size (0 ≤ var ≤ 1 or maybe -1000000 ≤ var ≤ 1000000).</paragraph>
