*“Complexity bounds for primal-dual methods minimizing the model of 
objective function**”*

**

/Abstract:/

/We provide Frank-Wolfe (Conditional Gradients) method with a 
convergence analysis allowing to approach a primal-dual solution of 
convex optimization problem with composite objective function. 
Additional properties of complementary part of the objective (strong 
convexity) significantly accelerate the scheme. We also justify a new 
variant of this method, which can be seen as a trust-region scheme 
applying the linear model of objective function. Our analysis works also 
for a quadratic model, allowing to justify the global rate of 
convergence for a new second-order method. To the best of our knowledge, 
this is the first trust-region scheme supported by the worst-case 
complexity bound./
