Description

Sets the best bound interval for MIP strategy.

When you set this parameter to best estimate node selection, the best bound interval is the interval at which the best bound node, instead of the best estimate node, is selected from the tree. A best bound interval of 0 (zero) means "never select the best bound node." A best bound interval of 1 (one) means "always select the best bound node," and is thus equivalent to nodeselect 1 (one).

Higher values of this parameter mean that the best bound node will be selected less frequently; experience has shown it to be beneficial to select the best bound node occaisionally, and therefore the default value of this parameter is 7.
