We can compose steps; but how do you compose score: Is it really environment reduction we're talking about here? I'm beginning to suspect that the performance score is a property of the agent, not the environment; this is consistent with the book's use of "reward" and "penalty.

The examples may be analogized from say how one would teach assembly language to someone who understands structured programming. Semantic relations The central relation is that imperative programming's denotational semantics is FP, FP's operational semantics is imperative programming.

Advantages and disadvantages of operational thinking. Environment In imperative programming there is a single implicit environment memory. In FP there are multiple environments; which could be explicit to the point of first classness the value of variables bound in environments could be other environments.

Use of environments to model data abstraction, various object frameworks, module systems. Semi Explicit Continuation Explicit in the sense that goto labels can be dealt with firstclassly as in assemblybut not explicit in the sense of capturing the entire future of a computation dynamic execution of a code block may be 'concave'.

Recursion iteration equivalence General principles as well as scheme semantics of tailrecursion. Type Issues Monomorphic, polymorphic and latent typing: Guile A variety of vehicles have been used for the imperative paradigm, eg. The current choice is Scheme in the guile dialect because it gives a full support for the functional and the imperative paradigm.

In fact Guile has been chosen over C because the single data structure in guile sexpressions is universal aka XML and thus imperative and functional thinking do not quarrel with datastructure issues.

Orthogonal kinds of abstractions, which are usually considered 'advanced', such as functional, higherorder functional, objectoriented, streambased, datadriven, language extensions via eval, via macros, via C can be easily demonstrated. In fact, once guile has been learnt, it is much faster to pick up C in the subsequent semester.

In addition to being a system programming and general purpose language Guile is also a scripting, extension and database programming language because it is the flagship language for FSF The free software foundation.

Nowadays this is known as instruction set architecture. In the more recent view, computer architecture has three parts: Here computer organization refers to the high-level, abstract or essential aspects of a machine's structure and behavior. The CO course is intended to give the basic architecture background that software professionals need.

In that sense it is a basic, first level course meant to provide the prerequisite for further study. However there is also an open, research oriented side to it.

In the earliest days of computing the programmer and the hardware engineer were the same person but across the next 50 years the two fields have separated so rigidly that they can hardly understand each other today. Recent trends are bringing these two trends back together. So a second ary aim of this course is make it a preliminary towards appreciating and participating in these trends.

Contents From a calculator to a stored-program computer The functionality of a calculator: Internal structure of a calculator that leads to this functionality.

Machine language and programs writing a sequence of instructions to evaluate arithmetic expressions. Computer or computing assistant in the traditional sense of the word, i. Parts of a computer: Processor CPUmemory subsystem, peripheral subsystem.

Ditto with the peripheral interface. Parts of these interfaces integrated with the processor, and the remainder contained in the chip-set that supplements the processor.

Two main parts of the processor apart from these interfaces: Three-address and one-address instructions and the corresponding data-path architectures, namely, general-purpose register architecture the classic RISC and accumulator architecture.

Zero-address instructions and the stack architecture. Just those concepts needed to understand CO: Ways of creating illusions or approximations of ideal memory.

On-chip and off-chip cache memories, redundant arrays of independent disks RAID. Improving the performance of a computer and increasing the usage of its subsystems by executing several instructions simultaneously. Analogy to assembly line manufacture of cars.Prim’s Algorithm.

Prim’s Algorithm also use Greedy approach to find the minimum spanning tree. In Prim’s Algorithm we grow the spanning tree from a starting position.

Unlike an edge in Kruskal's, we add vertex to the growing spanning tree in Prim's. Algorithm Steps: Maintain two disjoint sets of vertices.

Why does a greedy method based algorithm find the correct shortest distance from the source to all other vertices in a directed graph? Is it possible to find the shortest path in an undirected graph from the source vertex to any other vertex if the graph contains negative edge.

Dijkstra algorithm is a greedy algorithm. It finds a shortest path tree for a weighted undirected graph. This means it finds a shortest paths between nodes in a graph, which may represent, for example, road networks; For a given source node in the graph, the algorithm finds the shortest path between source node and every other node.

Vol.7, No.3, May, Mathematical and Natural Sciences. Study on Bilinear Scheme and Application to Three-dimensional Convective Equation (Itaru Hataue and Yosuke Matsuda). Apr 09, · In this video I show how a greedy algorithm can and cannot be the optimal solution for a shortest path mapping problem.

As with the majority of algorithm problems, it is key to understand the data that you will be dealing with, or else you could end up with a very poor performing solution. Find out how much developers like you are making with our Salary Calculator, now updated with Developer Survey data.
