The remark is that the recent work in this Bulletin dealing with the extension of a partial to a total strict order on a module over a partially ordered ring falls under standard order extension results for operator groups once it is noted that the added requirement of strictness just comes to injective operation of the positive scalars. These standard results are in turn generalized to a universal algebra setting.

Shopee was the largest e-commerce platform in Southeast Asia in 2020 by gross merchandise value and total orders. It is currently one of the leading e-commerce platforms in Malaysia. Despite the intense competition in the e-commerce space, Shopee has expanded aggressively across the Southeast Asian region over the last few years. Its successful business expansion is likely attributed to its profound competitive advantages. This study aims to examine the primary factors influencing customer satisfaction towards using Shopee for online purchasing in Malaysia. A survey questionnaire was used for data collection. A total of 100 Shopee users from Malaysia responded to the survey. The findings revealed that perceived ease of use and perceived convenience had influenced the customer satisfaction toward online purchasing on Shopee in Malaysia. Meanwhile, perceived usefulness and perceived trust did not significantly influence customer satisfaction towards Shopee in Malaysia. This study provides Shopee with valuable insights and guidance on customers’ perception of Shopee, leading to improved customer satisfaction.

AbstractWe construct total orders on the vertex set of an oriented tree. The orders are based only on up-down counts at the interior vertices and the edges along the unique geodesic from a given vertex to another.As an application, we provide a short proof (modulo Bass–Serre theory) of Vinogradov’s result that the free product of left-orderable groups is left-orderable.

This paper investigates the problems arising in the construction of a program to play the game of contract bridge. These problems include both the difficulty of solving the game's perfect information variant, and techniques needed to address the fact that bridge is not, in fact, a perfect information game. GIB, the program being described, involves five separate technical advances: partition search, the practical application of Monte Carlo techniques to realistic problems, a focus on achievable sets to solve problems inherent in the Monte Carlo approach, an extension of alpha-beta pruning from total orders to arbitrary distributive lattices, and the use of squeaky wheel optimization to find approximately optimal solutions to cardplay problems. GIB is currently believed to be of approximately expert caliber, and is currently the strongest computer bridge program in the world.

AbstractOrdinal classifier cascades are constrained by a hypothesised order of the semantic class labels of a dataset. This order determines the overall structure of the decision regions in feature space. Assuming the correct order on these class labels will allow a high generalisation performance, while an incorrect one will lead to diminished results. In this way ordinal classifier systems can facilitate explorative data analysis allowing to screen for potential candidate orders of the class labels. Previously, we have shown that screening is possible for total orders of all class labels. However, as datasets might comprise samples of ordinal as well as non-ordinal classes, the assumption of a total ordering might be not appropriate. An analysis of subsets of classes is required to detect such hidden ordinal substructures. In this work, we devise a novel screening procedure for exhaustive evaluations of all order permutations of all subsets of classes by bounding the number of enumerations we have to examine. Experiments with multi-class data from diverse applications revealed ordinal substructures that generate new and support known relations.
