Dijkstra’s single-source shortest-path algorithm (DA) is one of the well-known, fundamental algorithms in computer science and related fields. DA is commonly taught in undergraduate courses. Uniform-cost search (UCS) is a simple version of the best-first search scheme which is logically equivalent to DA. In this paper I compare the two algorithms and show their similarities and differences. I c...

This paper provides a deep insight into the learning mechanisms of UCS, a learning classifier system (LCS) derived from XCS that works under a supervised learning scheme. A complete description of the system is given with the aim of being useful as an implementation guide. Besides, we review the fitness computation, based on the individual accuracy of each rule, and introduce a fitness sharing ...

The large amounts of construction waste (CW) generated yearly and its high landfilled proportion worldwide motivate the search for sustainable solutions. Thus, effect sandy soil partial replacement in cemented mixtures was assessed present work terms mechanical behavior microstructure. Distinct cement contents, compaction efforts, curing periods were evaluated from soil-waste S75W25, S50W50, S2...

The extraction of models from data streams has become a hot topic in data mining due to the proliferation of problems in which data are made available online. This has led to the design of several systems that create data models online. A novel approach to online learning of data streams can be found in Fuzzy-UCS, a young Michiganstyle fuzzy-classifier system that has recently demonstrated to b...

A valuable experimental model for the pathogenesis of anxiety disorders is that they originate from a learned association between an intrinsically non-aversive event (Conditioned Stimulus, CS) and an anticipated disaster (Unconditioned Stimulus, UCS). Most anxiety disorders, however, do not evolve from a traumatic experience. Insights from neuroscience show that memory can be modified post-lear...

It is of great significance to study the effect solid contents (SC), binder-to-tailings (b/t) ratio, types and dosage fly ash (FA) on viscosity (V) uniaxial compressive strength (UCS) backfill. can improve filling efficiency reduce costs understand relationship between SC, b/t FA viscosity, UCS Consequently, this paper carried out compression tests rheological five different backfill specimens....

Abstract Uniaxial Compressive Strength (UCS) is a key indicator of the mechanical properties rock, particularly in diagnostic and restoration phases when stones are employed as construction material. In historical buildings, it important to determine UCS values without utilizing tests that involve destructive rock sampling. To estimate UCS, non-destructive techniques, such ultrasonic pulse velo...

a literature review revealed that most of the empirical equations introduced for determination of the uniaxial compressive strength (ucs) of rocks based on the schmidt hammer rebound number (n) are not sufficiently reliable mostly due to the relatively low coefficient of correlations. this is attributed to the fact that in most cases one formula is used for all types of rocks, although...
