Solving Math Problems Approximately: A Developmental Perspective
Although solving arithmetic problems approximately is an important skill in everyday life, little is known about the development of this skill. Past research has shown that when children are asked to solve multi-digit multiplication problems approximately, they provide estimates that are often very far from the exact answer. This is unfortunate as computation estimation is needed in many circum...
متن کاملA Graphical Approach for Solving Single Machine Scheduling Problems Approximately
For five single machine total tardiness problems a fully polynomial-time approximation scheme (FPTAS) based on a graphical algorithm is presented. The FPTAS has the best running time among the known approximation schemes for these problems.
متن کاملSolving mathematical problems - a personal perspective
Authored by a leading name in mathematics, this engaging and clearly presented text leads the reader through the various tactics involved in solving mathematical problems at the Mathematical Olympiad level. Covering...
متن کاملApproximately Solving Set Equations
Unification with constants modulo the theory ACUI of an associative (A), commutative (C) and idempotent (I) binary function symbol with a unit (U) corresponds to solving a very simple type of set equations. It is well-known that solvability of systems of such equations can be decided in polynomial time by reducing it to satisfiability of propositional Horn formulae. Here we introduce a modified...
متن کاملSolving Tourist Trip Design Problems from a User's Perspective
This position paper briefly motivates an abstract model for tourist trip design problems and outlines two scenarios we are working on: 1. a city trip planner to recommend a sequence of items for visiting a city, and 2. a travel region recommender for combining travel regions to recommend a composite trip. 1 Motivation, Abstract Model and Use Cases Tourist Trip Design Problems (TTDP) deal with t...
