..... There are 2 holes for each edge in the graph and each hole consists of 3 vertices. Therefore, the polygon consists of 6m 2n vertices. It is known in computational geometry that the coordinates of intersection points of lines with rational coefficients can be expressed with polynomial length [8]. All of the points in our construction are of this type. Therefore, the construction is polynomial. The transformation of a feasible solution can obviously be done in polynomial time. We obtain our inapproximability result, again, by using the technique of gap preserving reductions, which ....

....the Voronoi diagram of A v , and preprocess the diagram for membership queries. A membership query returns, for a give point p, the face of the Voronoi diagram where p lies. The preprocessing time for constructing the Voronoi diagrams is O(n log n) per level in T (see, for example, Chapter 20.2 of [8]) for a total of O(n log n) The space requirement is O(n) per level of T , for a total of O(n log n) Preprocessing a node v for membership queries also takes time O(jA v j log jA v j) and space O(jA v j) and a query can be answered in time O(log jA v j) see, for example, Chapter 30.3 of ....

[8] for a total of O(n log n) The space requirement is O(n) per level of T , for a total of O(n log n) Preprocessing a node v for membership queries also takes time O(jA v j log jA v j) and space O(jA v j) and a query can be answered in time O(log jA v j) see, for example, Chapter 30.3 of [8]) The total time is O(n log n) and the total space is O(n log n) With this data structure, given any node v in T , and a point p, one can find whether a disk in the subtree rooted at v covers p in time O(log n) by finding out in which cell of the Voronoi diagram of A v p lies, and ....

.... this is a triple (D, is a set of possible queries, and Q is a rule Note that despite the algorithmic flavor of the question, the error model is indeed cryptographic (i.e. adversarial) Note that the most efficient normal algorithm for range queries has complexity O( m 1) log N) [13]. We do not know how to make it data robust, however, without increasing the complexity by a factor of log N . which associates an answer a q,D = Q(q, D) with every query database pair q # D. Suppose we have a query structure (D, Q) A data robust algorithm (DRA) for these consists of ....
....D whose key (xkey, ykey) lies in q. In this section we give a simple, efficient DRA for range queries and show how to modify it to make an efficient consistent query protocol. 5. 1 A data robust algorithm for range queries Various data structures for efficient orthogonal range queries exist (see [13] for a survey) The most efficient (non robust) solutions have query time O( m 1) log N) for d dimensional queries. In this section we recall the construction of multi dimensional range trees (due to Bentley [3] and show how they can be queried robustly. The query time of the robust ....
