Introduction 1
Network is a technique used for planning and scheduling of large projects in the fields of construction, maintenance, fabrication, purchasing, computer system instantiation, research and development planning etc. There is multitude of operations research situations that can be modeled and solved as network. Some recent surveys reports that as much as 70% of the real-world mathematical programming problems can be represented by network related models. Network analysis is known by many names _PERT (Programme Evaluation and Review Technique), CPM (Critical Path Method), PEP (Programme Evaluation Procedure), LCES (Least Cost Estimating and Scheduling), SCANS (Scheduling and Control by Automated Network System), etc
This chapter will present three of algorithms.
1. PERT & CPM
2. Shortest- route algorithms
3. Maximum-flow algorithms
The document discusses control structures and flowcharts. There are three types of control structures: sequence, selection, and repetition. Sequence executes statements in order. Selection chooses between alternatives using conditional statements. Repetition repeats a block of code. Flowcharts use graphic symbols to represent program logic and flow. Common symbols include terminals, flow lines, and connectors. Flowcharts are similar to pseudocode and can model algorithms to solve problems.
Accelerating Dynamic Time Warping Subsequence Search with GPUDavide Nardone
Many time series data mining problems require
subsequence similarity search as a subroutine. While this can
be performed with any distance measure, and dozens of
distance measures have been proposed in the last decade, there
is increasing evidence that Dynamic Time Warping (DTW) is
the best measure across a wide range of domains. Given
DTW’s usefulness and ubiquity, there has been a large
community-wide effort to mitigate its relative lethargy.
Proposed speedup techniques include early abandoning
strategies, lower-bound based pruning, indexing and
embedding. In this work we argue that we are now close to
exhausting all possible speedup from software, and that we
must turn to hardware-based solutions if we are to tackle the
many problems that are currently untenable even with stateof-
the-art algorithms running on high-end desktops. With this
motivation, we investigate both GPU (Graphics Processing
Unit) and FPGA (Field Programmable Gate Array) based
acceleration of subsequence similarity search under the DTW
measure. As we shall show, our novel algorithms allow GPUs,
which are typically bundled with standard desktops, to achieve
two orders of magnitude speedup. For problem domains which
require even greater scale up, we show that FPGAs costing just
a few thousand dollars can be used to produce four orders of
magnitude speedup. We conduct detailed case studies on the
classification of astronomical observations and similarity
search in commercial agriculture, and demonstrate that our
ideas allow us to tackle problems that would be simply
untenable otherwise.

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.
