Research Description
Design of a new problemoriented hardware and a specialized software is now of growing interest since parallelization of computations became widely accepted in many application areas in which reducing the total computation time is a key factor.
New processor architectures can speed up operations which are essential for given classes of applications. For instance, in parallel solving of various combinatorial problems, parallel generation of combinatorial objects as problem instances is often required. Therefore, specialized procesors copying with this class of problems need fast hardware generators of basic combinatorial configurations, like permutations, combinations, partitions, trees, etc.
Many sequential and parallel algorithms for generation of combinatorial objects were developed in various low level models of parallel computations (associative, network, linear array, complex parallel counter etc.), sometimes with new representations and in new linear orders. In addition ranking and fast unranking algorithms for many classes of combinatorial objects were designed mostly on the basis of dynamic programming paradigm. They can be used for splitting the whole set to be generated into subsets and thus enabling parallel generation on the set level, for sequential/parallel random generation, etc. I designed several versatile, programmable hardware generators of permutations, derangements, combinations and partitions suitable for FPGA/ASIC implementation, which can be applied for fast mask and pattern generation in associative processors.
Among fast parallel processors speeding up computations dominated by relational algebra operations, an interesting proposition is an associative processor with multicomparand multisearch operations in which processing time does not depends on the sizes of comparand and data sets, but it is a function of the constant word size. Two FPGAimplementations of such specialized processors with builtin set of logical operators were developed for the first time in 2002 and 2008. The associative graph processor (AGP) is one of the core applications of such processor architecture.
Important research area is developing parallel metaheuristics for solving hard combinatorial optimization problems, like graph coloring, scheduling, TSP etc. For the graph coloring problem (GCP) parallel metaheuristics (PGA and PSA) were developed for the first time. They were tested on DIMACS graph coloring instances. Later PGA was used for solving graph coloring sum problem (GCS). The related publication with some theoretical and experimental results initialized research on using metaheuristics and other techniques to improve upper bounds on chromatic sum and chromatic sum number. For many DIMACS graph coloring instances the exact values of those parameters were found. Another interesting research is related to the robust graph coloring problem (RGCP). The original problem statement was reformulated in order to make it practical for robust system designers and then tested on special DIMACSderived and random graph instances. Many developed metaheuristic introduced new operators and hybridization techniques.
On the basis of theoretical results obtained at Cracow University of Technology by prof. Adam Kapralski (19482010) an academic software tool "PKmin" for synthesis and functional decomposition of combinational logic circuits was developed and is freely available for researchers and students.

Teaching Description
Before 1994 at the Cracow University of Technology I was conducting lectures, exercises and lab session for the courses : "Foundations of Control Engineering", "Control Theory", "Automata Theory", "Logic Design" and some others.
In the period 19941997 at the University of Aizu I was involved in teaching "Computer Literacy", "Algorithms and Data Structures", "Logic Design" and the extracurriculum student project "Generation of combinatorial objects in parallel".
At present I conduct the following courses at the Cracow University of Technology:

 Programming and Control of Industrial Robots
In March 2020 all active courses were moved to CUT elearning platform .
In the previous years I lectured courses on:
 Parallel and Distributed Processing
 Information Technologies
 Algorithms and Data Structures
 Design and Analysis of Computer Algorithms
 Information Processing Systems
 Computational Complexity
 Teaching Computer Literacy
 Computer Control Systems
 Programmable Logic Design
 Programmable Digital Systems
 Microcontroller Systems
In 1998 I established Laboratory of Programmable Digital Systems supervising its activities for over 20 years within the framework of Xilinx University Program.
I supervised about 60 theses for M.Sc.E.E., M.Sc.C.S., B.E.E.E. and B.E.C.S. degrees.
Many graduate students join my research activities and are coautors of publications in conference proceedings and computer science journals.
Educational Projects
In 20102015 I was conducting an EU project at CUT within the frame of OP Human Capital with 286 student and 20 faculty participants link .
