Tutorial COMP20007 Design of Algorithms Week 4 Workshop Solutions 1. Solving recurrence relations Solve the following recurrence relations, assuming T (1) = 1. (a) T(n)=4n−3 T (n) = T (n−1)+4 means T (n−1) = T ((n−1)−1)+4 = T (n−2)+4, and T (n−2) = T (n−3)+4, and so on. Repeatedly substitute into the first equation, until

Tutorial COMP20007 Design of Algorithms Week 6 Workshop 1. Topological sorting A topological ordering of a directed acyclic graph (DAG) is a way of sorting the nodes of the graph such that all edges point in one direction: to nodes later in the ordering. One of the algorithms discussed in lectures involves running a DFS

Tutorial COMP20007 Design of Algorithms Workshop 7 Solutions 1. Negative edge weights Your friend’s algorithm might sound like a good idea, but it sadly won’t cure Dijkstra’s algorithm of its inability to handle negative edge weights properly. Simply adding a constant value to the weight of each edge distorts the length of paths differently depending
