  The construction of uniform designs (UDs) has received much attention in
computer experiments over the past decades, but most of the previous works
obtain uniform designs over a U-type by lattice domain. Due to increasing
demands for continuous factors, UDs over the continuous domain is in lack.
Moreover, the uniformity can be further improved over a continuous domain. In
this paper, we use coordinate descent methods with an initialization derived by
threshold accepting (TA) algorithm to construct UDs over a continuous domain
with Centered $L_2$-discrepancy. The new UDs perform better than the recorded
ones in several computer experiments by the Kriging modeling.
