class ecyglpki.IPointControls

The interior point solver control parameter object

>>> r = IPointControls()

msg_lev

The message level, a str

The possible values are

• 'no': no output
• 'warnerror': warnings and errors only
• 'normal': normal output
• 'full': normal output and informational messages

>>> r.msg_lev  # the GLPK default
'full'
>>> r.msg_lev = 'no'
>>> r.msg_lev
'no'

ord_alg

The ordering algorithm used prior to Cholesky factorization, a str

The possible values are

• 'orig': normal (original)
• 'qmd': quotient minimum degree
• 'amd': approximate minimum degree
• 'symamd': approximate minimum degree for symmetric matrices

>>> r.ord_alg  # the GLPK default
'amd'
>>> r.ord_alg = 'qmd'
>>> r.ord_alg
'qmd'
