半定规划内点方法的图灵模型复杂性

On the Turing model complexity of interior point methods for semidefinite programming

Etienne de Klerk, Frank Vallentin

摘要:

众所周知,人们可以在多项式时间内使用椭球方法(在某些假设下)求解半定规划到固定精度。在本文中,它表明,同样适用于当一个使用短的步骤,原始内点方法。证明的主要思想是在每次迭代中使用丢番图逼近来限制迭代的中间位大小。

英文摘要:

It is known that one can solve semidefinite programs to within fixed accuracy in polynomial time using the ellipsoid method (under some assumptions). In this paper it is shown that the same holds true when one uses the short-step, primal interior point method. The main idea of the proof is to employ Diophantine approximation at each iteration to bound the intermediate bit-sizes of iterates.
