Correct predictions are in blue. If we detect only a subset of a labelled sentence, we highlight the caught part as blue, the missing part light blue. False positives are in green and false negatives are in red.

Problem 119 (Celular Frequency Assignment) — Constraint detection

The frequency-allocation problem consists of allocating frequencies to a number of transmitters so that there is no interference between transmitters and the number of allocated frequencies is minimized . The problem described here is an actual cellular phone problem where the network is divided into cells , each cell containing a number of transmitters whose locations are specified . The interference constraints are specified as follows : the distance between two transmitter frequencies within a cell must not be smaller than 16 ; the distances between two transmitter frequencies from different cells vary according to their geographical situation and must be at least equal to the values described in a given matrix . The problem of course consists of assigning frequencies to transmitters to avoid interference and , if possible , to minimize the number of frequencies .
