WebOct 21, 2016 · Algorithm I implemented. Loop: take a random edge (actually in order it was given); if we can add it to our matching then add; Finally we get a matching. The proof of condition from given section by contradiction: let's compare our matching with the maximum one. Let's consider one edge from our matching. WebMar 21, 2024 · Greedy is an algorithmic paradigm that builds up a solution piece by piece, always choosing the next piece that offers the most obvious and immediate benefit. So …
