Since the outbreak of COVID-19 pandemic, scholars have presented publications discussing a shift tourism towards higher level sustainability. Many argue that in 2020, people were not able to travel as usual and therefore could discover added value sustainable vacation through new experiences new, often domestic destinations. Using quantitative online panel-based study five European countries US...

This paper presents evolution algorithm for solving small (up to 32 nodes) traveling salesman problems with constraints. This new differential evolution algorithm with only two parameters the size of the population and the size of the generations use the Lehmer code of the permutation for the representation of populations. Experience with small instances of TSP with time windows and deadline TS...

1. The TPP is of critical importance to Taiwan. Its importance and implications are reflected in three major aspects. First is the economic implication if Taiwan joins (or failed to join) the TPP bandwagon. Second is the implication on domestic reforms, i.e. using TPP as a driving force for Taiwan to undertake reform initiatives. Last but not least is the political implication for Taiwan as a p...

among numerous np-hard problems, the traveling salesman problem (tsp) has been one of the most explored, yet unknown one. even a minor modification changes the problem’s status, calling for a different solution. the generalized traveling salesman problem (gtsp)expands the tsp to a much more complicated form, replacing single nodes with a group or cluster of nodes, where the objective is to fi...

conclusions: thus, identifying the hf patients before the flight and providing them proper education about the events that may occur during flight is necessary. results: hf patients are more prone to experience respiratory distress, anxiety, stress, cardiac decompensation, and venous thromboembolism (vte) during air travel. although stable hf patients can tolerate air travel, but those with acu...

This article deals with two versions of the traveling purchaser problem. In the uncapacitated version, the number of units of a given product available at any market where it is sold is either larger than or equal to the demand. In the capacitated version, the availability may be smaller than the demand. This study extends some known heuristics and presents some new ones capable of solving eith...

In this paper, Exp-function and (G′/G)expansion methods are presented to derive traveling wave solutions for a class of nonlinear space-time fractional differential equations. As a results, some new exact traveling wave solutions are obtained.

in this article, we apply the multiquadric radial basis function (rbf) interpo-lation method for nding the numerical approximation of traveling wave solu-tions of the kawahara equation. the scheme is based on the crank-nicolsonformulation for space derivative. the performance of the method is shown innumerical examples.

Before traveling, tourists need to ensure that they will have a well-organized trip, which mainly involves a smooth flow of visits to different tourist attractions by themselves or following a pre-designed plan made by tourism service providers. The present study examined how the sequence of visiting tourist attractions influences tourist satisfaction at the expectation and experience levels. P...
