Unfortunately, students drop out of programming courses because students think that programming is difficult to understand. The student's understanding of the problem definition is one of the drawbacks that hin
3 Problem Definition In an Online Judge (OJ) system, assuming there are \(\left| S \right|\) learners and \(\left| E \right|\) programming problems, the learner’s online learning behavior sequence is defined as: \(s=\{\left({e}_{1},{f}_{1}\right),\left({e}_{2},{f}_...
The American National Standards Institute (ANSI) proposed a standardised definition of the C language (ANSI committee X3J11). Most commercial C compilers and interpreters are expected to adopt the ANSI standard. C has the feature of high level programming language as well as the low-level ...

In this problem, the aim is to find the optimal value of N, which maximizes the profit PN. From the problem definition, the range of N is 0≤N≤18 The critical point(s) of PN are found by calculating the derivative of the profit function: P′N=100EWTN−5EWTN2−1,000,000N′P...
Do note that a single node is also considered a valid simple path under this definition. Please refer to the examples and notes below for instances. Input The first line of input contains two space-separated integers n and m (1 ≤ n ≤ 109, 0 ≤ m ≤ 4)— the ...
One of the possible solutions is to reduce the value of the flow on the second edge by 1. In the fourth sample, there is isolated circulation of flow, but this description is correct by definition.Codeforces (c) Copyright 2010-2025 Mike Mirzayanov The only programming contests Web 2.0 ...
This paper presents a distributed approach to optimal power flow (OPF) in an electrical network, suitable for application in a future smart grid scenario where access to resource and control is decentralized. The non-convex OPF problem is solved by an au
Since we know that the set of separable states has to form a convex set in the Hilbert space, we assume that any classification algorithm based on a particular distance definition would learn exactly this feature. For this purpose we exploited a “nearest neighbor” algorithm, classifying a clas...
Calculate all the trip distances, assuming that the earth is flat in order to use the Pythagorean rule. Get dist = hypot(stopsLat(idxs(:,1)) - stopsLat(idxs(:,2)), ... stopsLon(idxs(:,1)) - stopsLon(idxs(:,2))); lendist = length(dist); With this definition of the dis...
