Request for comments -- proposal to allow custom binary operators.
I'll looking for comments on custom binary operators: would it be useful,
if so, what use-cases do you have?
The most obvious and often-requested use-case would be for a form of
logical operator (AND, OR, XOR) that is distinct f

Oh, that's a let-down. Operator symbols get their expressive value from

I've never found a need for custom binary operators.
I can imagine some *theoretical* cases where they might be useful (but

Probably wise.
Hello guys. I'm having an issue with a Python PulP MILP problem. You can find
the simplified code that reproduces the problem here:
from pulp import *
machines = 2
I = range(machines)
positions = 2
J = range(positions)
years = 10
T = range(years)
age = {0: 5, 1: 7}
IR = 0.06
df = 0.3
costs = {

You can make these things easier to debug by breaking your code into small
functions. If there were s
The highest version of openssl available on my system is 1.0.0 which

I've installed 1.1.0 to a custom location /home/fetch/opt. But if I do
import ssl
ssl.OPENSSL_VERSION
it still shows me that it is using the system default 1.
