<p><big>Graph exploration</big></p>
<p>The problem of graph exploration can be seen as a variant of graph traversal. It is an <a href="page.php?w=Online_algorithm">online problem</a>, meaning that the information about the graph is only revealed during the runtime of the algorithm. A common model is as follows: given a connected graph 1=''G'' = (''V'', ''E'') with non-negative edge weights. The algorithm starts at some vertex, and knows all incident outgoing edges and the vertices at the end of these edges--but not more. When a new</p><p>
