Necessary Optimality Conditions for Non-smooth Continuous-Time Problems‎ ‎Using Convexificators

Ali Ansari Ardali

Volume 5, Issue 1 , January 2020, Pages 1-13

https://doi.org/10.30473/coam.2021.56443.1154

Abstract
  In this paper, ‎we develop general necessary optimality conditions of the KKT types for non-smooth continuous-time optimization problems with inequality constraints‎. ‎The primary instrument in our study is the concept of a convexificator‎. ‎Based on this concept‎, ‎non-smooth ...  Read More

Applying Duality Results to Solve the Linear Programming Problems with Grey Parameters

Farid Pourofoghi; Davood Darvishi Salokolaei

Volume 5, Issue 1 , January 2020, Pages 15-28

https://doi.org/10.30473/coam.2021.56072.1152

Abstract
  Linear programming problems have exact parameters‎. ‎In most real-world‎, ‎we are dealing with situations in which accurate data and complete information are not available‎. ‎Uncertainty approaches such as fuzzy and random can be used to deal with uncertainties in real-life‎. ...  Read More

A Fuzzy Distance Measure for Fuzzy Numbers

Gholamreza Hesamian

Volume 5, Issue 1 , January 2020, Pages 29-39

https://doi.org/10.30473/coam.2021.44290.1105

Abstract
  A fuzzy distance measure is introduced in this paper to evaluate the fuzzy distance between two fuzzy numbers‎. ‎For this purpose‎, ‎alpha-values of fuzzy numbers are used to develop an integral-based fuzzy distance measure‎. ‎The properties of the proposed fuzzy distance measure ...  Read More

An Efficient Data Collection Algorithm to Estimate Unknown Target Parameter in Wireless Sensor Networks

Amir Hosein Mohajerzadeh; Abbas Ali Rezaee; Morteza Bigdeli

Volume 5, Issue 1 , January 2020, Pages 81-101

https://doi.org/10.30473/coam.2020.50322.1131

Abstract
  Estimating the target parameter while the prior distribution function is known‎, ‎and several observations which are provided by the sensor node is the main goal in this paper‎. ‎In wireless sensor networks (WSN)‎, ‎nodes sense the environment and send data to a sink node called ...  Read More
