[sage-support] memory leak when copying Coin linear program

The following code quickly consumes all available memory on the machine: sage: P = MixedIntegerLinearProgram(solver="Coin") sage: P.add_constraint(P[0]+P[1]==1) sage: while True: : P = copy(P) : w = solve(P) A ticket has been opened, #12004. If the solver is GLPK, however, this issue

[sage-support] if statements and arguments in sage

Hi folks, When I try and do to two arguments in the same lines in sagemath it does not compute, this is what I have written: if A==1 and D==1 then case <- 1 else if A==2 and D==1 then case <- 2 and if case==1 then probsy <- list1 and probsz <- list1 else if case==2 then probsy <- lis
