    "Always check result.getState().isOptimal() - or isFeasible() when a time limit is set - before reading values. After an INFEASIBLE or UNBOUNDED result Variable.getValue() returns null.",

    "Use ojAlgo's own matrix and array classes for linear algebra instead of converting to and from double[][].",
    "Do not use old names that no longer compile: Variable.make and addVariable(Variable) are now model.newVariable(name); PrimitiveMatrix and Primitive64Matrix are MatrixR064; PrimitiveDenseStore and Primitive64Store are R064Store. See https://www.ojalgo.org/updating-old-code/"
