Member Data Documentation

epsilon

double epsilon

Relative gap value allowed. For exact solving, epsilon = 0 (default).

gamma

float gamma

Gamma parameters, needed for the computation of the lambda update step

limit_lb

float limit_lb

not used anymore, should be removed

max_iteration

int max_iteration

Maximum iteration number of sub-gradient descent for each problem / sub-problem.

max_node

int max_node

Maximum visited node number during the Branch and Bound process.

theta

float theta

Theta parameters, used to dynamicaly change Gamma during Sub-Gradient Descent process.

time_limit

double time_limit

Maximum computation time allowed for the Branch and Bound process.
