To do so, we must address challenges introduced by real- life large graphs: • The irregular structure of real graphs leads to poor paral- lelism. In general, the logic of a partitioning algorithm is complex and many computation steps may depend heavily on each other, leading to poor ...
Surely, it is beneficial to have a code reference for many algorithms and data structures, but I also think that just superficially knowing the algorithm and maybe having implemented it once or twice before is sufficient to use it without a reference? — Some other Codeforces grandmaster Therefor...
We prove a tight lower bound which shows that our algorithm is optimal up to constants. Our algorithm uses a primal dual convex programming scheme. To the best of our knowledge this is the first time that such a scheme is used in the online framework. We also discuss an application of ...
The greedy algorithm is based on looking at the i for which the next applicable p'_j in D_i is the largest. With our formalism, this defines as follows.Definition 13 (Greedy Strategy). Let s be a strategy for D. We say that s is greedy if ...
In model-based RL, the samples are used to learn a dynamics model of the environment, which in turn is used in a planning or optimal control algorithm to produce a policy or the sequence of controls. In model-free RL, the dynamics are not explicitly modeled, but instead the optimal ...

Greedy algorithmThis paper studies the following variant of clustering or laying out problems for directed acyclic graphs (DAG for short), called the minimum block transfer problem. The objective of this problem is to find a partition of a node set which satisfies the following two conditions: (...
Studies have shown that as a species we prefer two birds in the hand to a potential five in the bush – if they come at the risk of a dead parrot. In other words, we’re more averse to loss than we’re greedy for gains.
Due to the orbital dynamics of low-altitude satellites, the task requests in this problem have negligible slack; i.e., the window size is equal to the request duration. Assuming that only one task can be scheduled per time window, the well-known greedy activity-selector algorithm [17] is...
