Real RAM Model. A memory cell stores a real number. Any single arithmetic operation or comparison can be computed in constant time. In addition, sometimes also roots, logarithms, other analytic functions, indirect addressing (integral), or oor and ceiling are used. This is a quite powerful (and somewhat unrealistic) model of computation. Therefore we have to ensure that we do not abuse its power. Algebraic Computation Trees (BenOr [1]). A computation is regarded a binary tree. The leaves contain the (possible) results of the computation. Every node v with one child an operation of the form +, −, , /, p,... is associated to. The operands of this operation are constant, input values, or among the ancestors of v in the tree. Every node v with two children a branching of the form> 0, 0, or = 0 is associated to. The branch is with respect to the result of v's parent node. If the expression yields true, the computation continues with the left child of v; otherwise, it continues with the right child of v. a − b ≤ 0 a − c b − c

"... In this paper we determine the amortized computational complexity of the dynamic convex hull problem in the planar case. We present a data structure that maintains a finite set of n points in the plane under insertion and deletion of points in amortized O(log n) time per operation. The space usage o ..."
