Professor in the field of computer science from the University of Kentucky, USA, Prof. Raphael Finkel gave a public lecture in front of students of the Faculty of Technology & Computer Science, Universitas Prima Indonesia (Unpri). The public lecture was also attended by the Rector of Unpri Prof. dr. Djakobus Tarigan AAI DAAK, Dean of the Faculty of Technology & Computer Science Abdi Dharma S.Kom M.Kom, Head of the Undergraduate Program-Informatics Engineering Mawaddah Harahap S.Kom M.Kom, Head of the Undergraduate Program-Industrial Engineering Fahri Zulmy ST MT, Secretary of the Undergraduate Program-Information Systems Siti Aisyah S.Kom M.Kom, Refi Ikhtiari PhD (Unpri Quality Assurance Institute) and Teng Sauh Hwee SE M.Si (coordinator of cooperation).

In the public lecture, Prof. Raphael Finkel delivered two lecture topics. In the first session, Prof. Raphael Finkel discussed programming languages, by introducing a functional programming language called ML and a logic programming language called Prolog. Then, in the second session, Prof. Raphael Finkel delivered 10 Algorithms that must be known by a student studying computer science.

Prof. Raphael Finkel explained that Algorithm means a tool to solve specific computational problems. In an algorithm there must be input as the material used, procedural steps to map input to output and of course must have output as the result of the computation.

He said, some aspects that must be considered in analyzing an algorithm are Correctness. The truth in question is the output produced by the algorithm according to what is desired or according to the facts that are in accordance with the computational calculations. Truth is related to accuracy and precision. Algorithm presentation can also be done in several forms, according to the target object of the presentation.

Algorithms are also related to data structures. The importance of data structures for organizing data storage in memory. One of the problems of computing is limited resources, one of which is memory. As we know that Prof. Raphael Finkel's earliest research was to create the first version of the Jargon File.
