Dijkstra Graphs
We revisit a concept that has been central in some early stages of computer science, that of structured programming: a set of rules that an algorithm must follow in order to acquire a structure that is desirable in many aspects. While much has been written about structured programming, an important issue has been left unanswered: given an arbitrary, compiled program, describe an algorithm to de...
متن کاملFormalizing Dijkstra
We present a HOL formalization of the foundational parts of Dijkstra’s classic monograph “A Discipline of Programming”. While embedding programming language semantics in theorem provers is hardly new, this particular undertaking raises several interesting questions, and perhaps makes an interesting supplement to the monograph. Moreover, the failure of HOL’s first order proof tactic to prove one...
متن کاملTheoretical Considerations for Viscoelastic Characterization of Biomaterials
Untuk sesuatu rekaan, pembinaan serta ujian jentera-jmtera memproses dan mesin-mesin pengangkutan bahan-bahan biological, sifat-sifat mekanikal bahan-bahan tersebut perlu diketahui terlebeh dahulu. Oleh kerana percubaan-percubaan yang lampau dapat mempastikan bahawa bahan-bahan biological bersifat viscoelastic, perlulah ianya dinyatakan supaya dapat dipastikan tindak balas sifat-sifat tersebut ...

Proof. There are three cases: (1) A and B are in the same column. Then, since in each column we picked the shortest student, A is shorter than B. (2) A and B are in the same row. Then, since in each row we picked the tallest student, B is taller than A. (3) A and B are neither in the same row, nor in the same column. Let C be a student who is in the same row as A and in the same column as B. Th...
