presolve returns error "unknown bound type INDICATORS" about papilo HOT 1 CLOSED

PaPILO currently does not support the INDICATORS.
This particular instance only contains two indicator constraints:

INDICATORS
 IF gen0      B15(0)    0
 IF gen1      B15(0)    1

Instead of ignoring the indicators I would rather I would recommend creating two instances one without B15(0) and gen0 and the other one without B15(0) and gen1. It might be the case that adding both constraints gen1 and gen0 might lead to infeasibility.
Generating two instances (in your case maybe just use one) would preserve more of the original structure.

Unfortunately, in PaPILO we can not skip the INDICATORS since in this case we want to the user decide how to proceed.

Btw: we are changing the error message to a (little bit) more descriptive explanation

from papilo.
