We prove that it is NP-hard to decide whether a polyhedral 3-ball can be triangulated with k simplices. The construction also implies that it is difficult to find the minimal trian...
Restoring binary images is a problem which arises in various application fields. In our paper, this problem is considered in a variational framework: the sought-after solution min...
This paper presents a quantum algorithm for finding minimal ESCT (Exclusive-or Sum of Complex Terms) or ESOP (Exclusiveor Sum Of Products) expressions for any arbitrary incomplet...
