Due to their fundamental role in theory and practice, clusterization and cut problems has always attracted a lot of attention. We establish a new connection between these two classes of problems by

We study the problem of computing the distance between two given configurations. We prove that if source and target configurations are maximal matchings,

Our aim is to identify structural properties (parameters) of graphs which allow the efficient solution of EDP without restricting the placement of terminals in . in any way. In this setting, EDP is known to

,Hamiltonicity Below Dirac’s Condition,2. Both the value ./2 and the requirement for . to have high degree are necessary for the theorem to hold..In this work we give efficient algorithms for determining Hamiltonicity when either of the two conditions are relaxed. More precisely, we show that the . problem can be solved in time ., for a
