A nonlinear optimization workflow that works in **Mathematica 11.2** (M11) gives different results in **Mathematica 14** (M14), even though the source code and input data are identical. The discrepancy appears in the `FindMinimum` step. *...
I am working on a Mathematica program to analyze fission yield data of U-235. The program calculates results for 5 different patterns based on neutron incident energies. While the calculation works correctly for pattern = 3, it produces errors for...
The attached code works in Mathematica 9 (see attached M9). But it doesn't work in Mathematica 14 (see M14). M9 and M14 are exactly the same, but the results are different when you calculate it in Mathematica 9 and Mathematica 14. The...
