Complexity Results for Structure-Based Causality

چکیده
We analyze the computational complexity of causal relationships in Pearl’s structural models, where we focus on causality between variables, event causality, and probabilistic causality. In particular, we analyze the complexity of the sophisticated notions of weak and actual causality by Halpern and Pearl. In the course of this, we also prove an open conjecture by Halpern and Pearl, and establish other semantic results. To our knowledge, no complexity aspects of causal relationships have been considered so far, and our results shed light on this issue.

Survey of Money- Output Causality: Case Study of Iran, Based on Vector Error Correction Model (VECM)
This study investigated the dynamic relationship between money, prices and output in a multivariate structure of casualty analysis in Iran for the two period of 1969 to 2012 (entire period) and 1989 to 2012 (sub-period). This statistical framework has been projected for situations where causal links may have changed over the sample period. Results of a three-variable Vector Error Correction Mod...
متن کاملThe Impact of the Economic Complexity Index on Competitiveness: A Study of Selected Emerging Countries
The main purpose of this study is to investigate the relationship between economic complexity and competitiveness using panel data in a sample of 39 emerging countries from 2002 to 2018. The results of the causality test of Dmitresco and Horlin Granger (2012) show a two-way cause between economic complexity and competitiveness. This indicates that the higher complexity of the economy helps coun...

متن کاملTime and Space Complexity Reduction of a Cryptanalysis Algorithm
Binary Decision Diagram (in short BDD) is an efficient data structure which has been used widely in computer science and engineering. BDD-based attack in key stream cryptanalysis is one of the best forms of attack in its category. In this paper, we propose a new key stream attack which is based on ZDD(Zero-suppressed BDD). We show how a ZDD-based key stream attack is more efficient in time and ...
