چکیده
Abstract Database queries are one of the most important functions a relational database. Users interested in viewing variety data representations, and this may vary based on database purpose nature stored data. The Air Force Institute Technology has approximately 100 logs which will be converted to standardized Scorpion Data Model format. A is designed house its associated sensor non-sensor metadata. Deterministic polynomial-time were used test performance schema against two other schemas, with databases 1000 repeated randomized Of these approaches, that had best was chosen as AFIT’s solution, now more complex useful need developed enable filter research. To end, consider combined Multi-Objective Knapsack/Set Covering Query. Algorithms address Set Problem or Knapsack could individually achieve results, but together they offer additional power potential user. This paper explores NP-Hard problem domain KP/SCP, proposes Genetic Hill Climber algorithms, implements algorithms using Java, populates their structures SQL from databases, finally compares how perform.

Solving a bi-objective project capital budgeting problem using a fuzzy multi-dimensional knapsack
In this paper, the researchers have proposed a multi-dimensional knapsack model for project capital budgeting problem in uncertain situation which has been modeled through fuzzy sets. The optimistic and pessimistic situations were considered and associated deterministic models were yielded. Numerical example has been supplied toillustrate the performance of proposed model. The results were prom...
متن کاملSolving efficiently the 0-1 multi-objective knapsack problem
In this paper, we present an approach, based on dynamic programming, for solving the 0-1 multi-objective knapsack problem. The main idea of the approach relies on the use of several complementary dominance relations to discard partial solutions that cannot lead to new non-dominated criterion vectors. This way, we obtain an efficient method that outperforms the existing methods both in terms of ...
متن کاملAn Improved Multi-objective Evolutionary Algorithm for Multi- Objective 0/1 Knapsack Problem
To further enhance the distribution uniformity and extensiveness of the solution sets and to ensure effective convergence of the solution sets to the Pareto front, we proposed a MOEA approach based on a clustering mechanism. We named this approach improved multi-objective evolutionary algorithm (LMOEA). This algorithm uses a clustering technology to compute and maintain the distribution and div...
متن کامل2 Set Covering Problem
In the previous lecture, we covered a series of online/offline edge-weighted Steiner tree/forest problems. This lecture extends the discussion to the node-weighted scope. In particular, we will study the nodeweighted Steiner tree/forest problem and introduce an offline O(logn)−approximation polynomial-time algorithm[KR95]. It is well known there is no polynormial-time algorithm that achieves o(...
متن کاملBi-objective Optimization of a Multi-product multi-period Fuzzy Possibilistic Capacitated Hub Covering Problem: NSGA-II and NRGA Solutions
The hub location problem is employed for many real applications, including delivery, airline and telecommunication systems and so on. This work investigates on hierarchical hub network in which a three-level network is developed. The central hubs are considered at the first level, at the second level, hubs are assumed which are allocated to central hubs and the remaining nodes are at the third ...
