The corresponding matrix Riemann problems are constructed for two-point as well as for multi-point correlators. Long-distance asymptotics of two-point correlators is calculated.

İlk olarak kısıtsız global optimizasyon problemlerini çözmek için önerilse de, çeşitli problem tiplerini içeren çok sayıda PSO çalışması mevcuttur. Fakat bununla birlikte, ilgili bilimsel yazından görülebileceği gibi, diğer uygulama türleriyle karşılaştırıldığında, kesikli ve 0-1 yapıdaki PSO uygulamaları görece daha az sayıdadır. Bu bağlamda, mevcut araştırmada, kuantum tabanlı yerel arama yordamı ile güçlendirilmiş bir 0-1 PSO modifikasyonu getirilmiştir. Bahsedilen kuantum tabanlı prosedür, algoritma tarafından bulunan eniyi çözüm etrafında üretilen bir küre içinde konumlanan ve kuantum parçacıkları olarak adlandırılan rastgele dağıtılmış parçacıklar üretir. Ardından bu parçacıklar, bulunan eniyi çözüm üzerinde olası iyileştirmeler sağlayabilmek için yerel arama amacıyla kullanılır. Önerilen yaklaşımın performansı, bu alanda sıkça kullanılan Bir-Enb, Aldatıcı, Plato ve Kral Yolu fonksiyonlarından oluşan bir 0-1 problem seti kullanılarak test edilmiştir. Deneysel çalışma, önerilen yaklaşımın 0-1 problemlerdeki etkinliğini göstermektedir.

In that limit the probability density develops shock waves, clearly contradicting the exact result. By an approximated analysis in the point on which these discontinuities appear, it is shown that their formulation is inhibited by quantum effects.
