Center node: "detecting simultaneous integer relations for several real vectors"
  Abstract: An algorithm which either finds an nonzero integer vector m for given t real n-dimensional vectors x1,��� , xt such that x T m = 0 or proves that no such integer vector with norm less than a given bound exists is presented in this paper. The cost of the algorithm is at mostO(n 4 + n 3 log�(X)) exact arithmetic operations in dimension n and the least Euclidean norm�(X) of such integer vectors. It matches the best complexity upper bound known for this problem. Experimental data show that the algorithm is better than an already existi ng algorithm in the literature. In application, the algorit hm is used to get a complete method for finding the minimal polyno mial of an unknown complex algebraic number from its approximation, which runs even faster than the corresponding Maple built-in function.
