*** threads (integer): global default thread count
threads = 8
*** lpmethod (integer): algorithm to be used for LP problems [4 = barrier]
lpmethod = 4
*** advind (integer): advanced basis use [0 = do not use advanced basis]
advind 0
*** reslim (integer): solve time limit in seconds [172800 seconds = 2 days]
reslim 172800
*** scaind (integer): matrix scaling on/off [1 = modified, more aggressive scaling method]
scaind 1
*** aggind (integer): aggregator on/off [5 = aggregator will be applied 5 times]
aggind 5
*** iis (boolean): run the conflict refiner also known as IIS finder if the problem is infeasible
iis 1

*## The settings below can reduce solve time substantially, but their impacts on the solution
*## have not yet been fully characterized, and some of them might do nothing. Use at your own risk.
*## Some background details are available at

*** numericalemphasis (boolean): emphasizes precision in numerically unstable or difficult problems [default 0]
* numericalemphasis 1
*** depind (integer): dependency checker on/off. 3 = turn on at beginning and end of preprocessing [default -1]
* depind 3
*** barcolnz (integer): specifies the number of entries in columns to be considered as dense [default 0]
*** commenting this out (i.e., setting back to zero) can improve solve time when running with hydrogen transport (GSw_H2=2)
barcolnz 100
*** barorder (integer): row ordering algorithm selection. 1 = approximate minimum degree (AMD) [default 0]
* barorder 1
*** baralg (integer): barrier algorithm selection. 1 = infeasibility-estimate start, 3 = standard barrier [default 0]
* baralg 3
*** barstartalg (integer): barrier starting point algorithm. 2 = default primal, estimate dual [default 1]
* barstartalg 2
*** scaind (described above)
* scaind 0
*** Can use bardisplay=2 to print more diagnostics about the barrier method and choice of barcolnz
* bardisplay 2
*** solutiontype (integer): type of solution (basic or non basic): 0 does basic with crossover, 2 skips crossover
* solutiontype 2
