RE: Simplex Algorithm
(12-22-2023 07:38 AM)ftneek Wrote:  I uploaded new source files with quite a few improvements. The biggest being that simplex() does not require you to manually enter any slack or artificial variables, and it is able to handle maximization problems, integer restrictions, binary restrictions, and unrestricted variables. Also simplex_int() accepts programs in canonical form, to match the change to simplex_core().

Wow! That is quite an update.

Unfortunately, this update crash HP Prime emulator 2.1.14181 (2018 10 16)

Start with a hard reset, then close emulator
copy OP *.hpprgm to "HP Prime\Calculators\prime" directory.
start emulator, Cas> test_simplex()      → {1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1}
restart emulator                                  → CRASHED

Problem seems to arise from simplex.hppgrm, not the others.
And, it is not because of binary nature of .hppgrm

Start with a hard reset
SHIFT PROGRAM NEW, name=simplex, copy actual #cas ... #end code
Cas>lpmax --> ∞
restart emulator ... failed
restart emulator, Cas> lpmax --> lpmax
restart emulator, Cas> lpmax --> ∞
restart emulator ... failed
restart emulator, Cas> lpmax --> lpmax
restart emulator, Cas> lpmax --> ∞
...
