HPM: A Computational Formalism for Heuristic Procedure Modification
نویسنده
چکیده
The HPM (Heuristic Procedure Modification) system is a model of strategy learning and optimization, implemented as a processing environment within the PRISM production system package [4]. This paper describes progress in getting HPM to emulate children's discoveries about basic addition procedures. HPM s goal-trace and production trace formalisms allow it to maintain a history of its actions which is both goal ordered and time ordered. Heuristics about meaningful patterns in these traces guide the construction of new productions, which modify procedures by replacing or circumventing preexisting productions.

A Heuristic Algorithm for Project Scheduling Problem to Maximizing the Net Present Value
This paper deals with resource unconstrained project scheduling problems with the objective of maximizing the net present value (NPV) of project cash flows. Here we present a heuristic algorithm named as differential procedure (Dif_AOA).

متن کاملA New Heuristic Solution Method for Maximal Covering Location-Allocation Problem with M/M/1 Queueing System
We consider the queueing maximal covering location-allocation problem (QM-CLAP) with an M/M/1 queueing system. We propose a new solution procedure based on decomposition of the problem into smaller sub-problems. We solve the resulting sub-problems both with a branch and bound algorithm and with the meta-heuristic GRASP. We also solve the entire model with GRASP. Computational results for these ...

Vehicle Routing Problem with Time Windows (VRPTW) is an NP-Complete Optimization Problem. Even finding an optimal solution for small size problems is too hard and time-consuming. The objective of VRPTW is to use a fleet of vehicles with specific capacity to serve a number of customers with dissimilar demands and time window constraints at minimum cost, without violating the capacity and time wi...
متن کاملA Heuristic Algorithm for Nonlinear Lexicography Goal Programming with an Efficient Initial Solution
In this paper, a heuristic algorithm is proposed in order to solve a nonlinear lexicography goal programming (NLGP) by using an efficient initial point. Some numerical experiments showed that the search quality by the proposed heuristic in a multiple objectives problem depends on the initial point features, so in the proposed approach the initial point is retrieved by Data Envelopment Analysis...
