ABC 355 D题Intersecting Intervals 题意现在有n条线段,每条线段的左端点和右端点依次给出,求有多少对线段有交集。思路考虑正难则反的想法,我们考虑着n条线段全部两两相交的时候,那么答案就是(n-1)*n/2,现在我们要求出有多少对线段是不相交的。 当两条线段不相交的时候,显然有其中一条线段的左端点严格大于另...

We consider the problem of optimizing the production planning with aggregation of operations and selection of their intensities for batch processing of a given family of products on a multi-position reconfigurable production system at specified (time) intervals under nonstationary...
Given two Cantor setsXandYin [0, 1), invariant under the mapx→b xmod 1, the Hausdorff dimension of (X+t)∩Yis constant almost everywhere. WhenX,Yare defined by admissible digits in baseb, and more generally by sofic systems, we compute this dimension in terms of the largest Lyapunov ex...
School lessons take place daily in two-hour intervals and are meant to cater to diverse school levels. However, despite the availability of TV- and radio-based lessons early on in the pandemic, relatively few students in Dhaka reported using these offerings as their primary form of learning ...
