In this paper, we propose an arc-search corrector-predictor interior-point method for solving $P_*(kappa)$-linear complementarity problems. The proposed algorithm searches the optimizers along an ellipse that is an approximation of the central path. The algorithm generates a sequence of iterates in the wide neighborhood of central path introduced by Ai and Zhang. The algorithm does not de...

We study the envy-free pricing problem in linear multi-unit markets with budgets, where there is a seller who brings multiple units of a good, while several buyers bring monetary endowments. Our goal is to compute an envy-free (item) price and allocation, i.e. an outcome where all the demands of the buyers are met given their budget constraints, which additionally achieves a desirable objective...

in this paper, downlink resource allocation for a sparse code multiple access (scma) based heterogeneous  cellular networks (hcn) is investigated. the main aim of this paper is to obtain joint power allocation and codebook assignment to achieve the least total system transmit power. in this regard, the proposed objective function is formulated as total transmit power subject to users minimum ra...

Although scanner price quotes and expenditures have great promise in improving the Consumer Price Index (CPI), their use has introduced new problems. One major problem confronting the Bureau of Labor Statistics (BLS) is the treatment of an item that experiences no purchases during a particular time period. Either a price can be explicitly imputed for this item or it can be implicitly imputed by...

we present a methodology for characterization and an approach for computing the solutions of fuzzy linear systems with lr fuzzy variables. as solutions, notions of exact and approximate solutions are considered. we transform the fuzzy linear system into a corresponding linear crisp system and a constrained least squares problem. if the corresponding crisp system is incompatible, then the fuzzy ...

After the exchange rate reform on August 11, 2015, RMB has had an increasing impact my country's stock price. The study of changes plays a very important role in stabilizing This paper first introduces transmission mechanism to prices from three aspects, and then establishes multiple linear regression equation, using closing price CSI 500 Index against US dollar as descriptive indicators rate, ...

Differential-algebraic equations with higher index give rise to essentially ill-posed problems. Therefore, their numerical approximation requires special care. In the present paper, we state the notion of ill-posedness for linear differential-algebraic equations more precisely. Based on this property, we construct a regularization procedure using a least-squares collocation approach by discreti...

In 1996 the Boskin report (1996) discussed several types of measurement errors in the consumer price index (CPI). The CPI measures the cost of purchasing a ...xed market basket of goods and services. All the goods and services in this basket can be divided over classi...cation levels beginning with major groups like food and beverages, housing, transportation, etc. The CPI calculates the monthl...

The Consumer Price Index (CPI) measures the average change over time in the prices paid by urban consumers for a representative market basket of consumer goods and services. The CPI for All Urban Consumers (CPI-U) represents the spending habits of about 87 percent of the population of the United States. The CPI for Urban Wage Earners and Clerical Workers (CPI-W), a subset of the CPI-U populatio...
