We study moduli stabilization in Calabi-Yau orientifold compactifications of type IIB string theory with O3- and O7-planes. We consider a Calabi-Yau three-fold with Hodge number h ^2 , 1 = 50 and stabilize all axio-dilaton and complex-structure moduli by three-form fluxes. This is a challenging task, especially for large moduli-space dimensions. To address this question we develop an algorithm to generate 10^5 flux vacua with small flux number N _flux. Based on recent results by Crinò et al. we estimate the bound imposed by the tadpole-cancellation condition as N _flux ≤ O $$ \mathcal{O} $$ (10^3), however, the smallest flux number we obtain in our search is of order N _flux = O $$ \mathcal{O} $$ (10^4). This implies, in particular, that for all solutions to the F-term equations in our data set the tadpole conjecture is satisfied.
